1. Introduction The objective of the task 'Data identification' (T5.1) was to identify relevant data available from Geological Surveys and other organizations (e.g., CGMW…), from European projects (e.g., ProMine, EuroGeoSource…), and other layers (geological [e.g., OneGeology Europe], geophysical and geochemical, dedicated layers to mineral potential at depth and to offshore/marine resources). Figure 1, which describes the general architecture of the EU-MKDP (Mineral Resources Knowledge Data Platform), summarizes how the knowledge base will be fed from these different sources.

Figure 1: General architecture of the EU-MKDP

The aim of this task was not to deliver an exhaustive inventory of available data. Instead of this, it was to get an enough precise idea (i) of the formats of these different data and (ii) how they are being served (or will be served) by their owner/provider in order to:

- ensure that the design of the EU-MKDP architecture and its components will be fully adapted to welcome all these datasets;

- define the exact perimeter of the task T5.4 dedicated to the support to Geological Surveys for web services implementation.

This report will successively review 'generic' data, with a particular focus on structured data provided by Geological Surveys (T5.1.1), data provided by other Minerals4EU WPs and how they will be integrated (T5.1.2), and will present the bases of the metadata system, with a special emphasis on the Catalogue Service for Web (CS-W).

2. Available 'generic' data identification Minerals4EU is strongly connected with EU-FP7 ongoing projects and with a DG Enterprise-commissioned project (Minventory). Figure 2 tries to map the connections between these different projects.

Figure 2: Interconnection of Minerals4EU with several other ongoing projects

Most of these projects have developed websites and geospatial web portals which allow exchanging data/information through web services (WMS and WFS).

2.1. Review of ongoing projects related to geology and mineral resources s.l.

► EGDI-Scope (http://www.egdi-scope.eu/) The objective of the EGDI-Scope project is to deliver an implementation plan for the concrete realization of a pan-European Geological Data Infrastructure. This Infrastructure will enable European geological surveys to serve and maintain INSPIRE-compliant, interoperable geological data and information reflecting our understanding of the subsurface. As such, EGDI-Scope sets of minimum criteria by which the datasets could be assessed. Another important objective is to create a framework to sustain results from past, on-going and future European projects (e.g. OneGeology Europe, EuroGeoSource, PanGeo, eMODNet, etc.). Representatives from different user communities involved in European policy, industry and research will be extensively engaged with regards to the implementation plan. An inventory of 80 previous and current European geological projects has been compiled (see EGDI-Scope D 3.1: Detailed Review of previous and ongoing projects; K A Lee, R W Armstrong, December 2012). Of these, 27 (34%) are classed as Natural Risk/Geohazard, 11 (14%) are developing Data Infrastructures, 10 (12%) and 7 (10%) are Economic resources/Energy and Geochemistry respectively. ► OneGeology Europe (http://www.onegeology-europe.org/ ; http://onegeology-europe.brgm.fr/geoportal/viewer.jsp) The main objective of OneGeology-Europe is to make geological spatial data held by European geological surveys both discoverable and accessible. OneGeology-Europe aims to create dynamic digital geological map data for Europe. It will make a significant contribution to the progress of the INSPIRE directive (i.e. develop systems and protocols to better enable the discovery, viewing, downloading and sharing of core European spatial geological data). OneGeology-Europe will address licensing and multi-lingual aspects of sharing geological knowledge and demonstrate best practice examples of the delivery and application of geological spatial data in the public and private sectors. One-Geology Europe produced a data portal and a multilingual geological metadata catalogue, INSPIRE compliant data and metadata, and web map services. ► EMODNet-Geology (http://www.emodnet-geology.eu/) The overall objective of the EMODNet project is to create pilot studies that assemble fragmented and inaccessible marine data into interoperable, contiguous and publicly available datasets for whole maritime basins. The EMODNet-Geology project is one of six preparatory action projects that, in addition to marine geology, bring together information on marine chemistry, marine biology, hydrography, sea-bed habitats and physical properties. Each project defines the processes, technologies and approximate costs of implementing a fully functioning European Marine Observation and Data Network. For the EMODNet-Geology project, the project partners are compiling data layers for the Baltic Sea, Greater North Sea and Celtic Sea.

6 of 24

Minerals4EU FP7-NMP2-CA-2013-608921

The delivery of the EMODNet-Geology data layers is being achieved through the adoption and adaption of technologies developed by the OneGeology-Europe (1G-E) project. The maritime map layers are being delivered using the 1G-E portal to allow the delivery of both onshore and offshore geological information via a single portal. The geology data available includes:

• sea-bed sediments; • sea-floor geology; • boundaries and faults; • rates of coastal erosion or accumulation; • geological events (submarine slides, earthquakes, etc.); • minerals.

► Minventory (http://www.minventory.eu/) The aim of this DG Enterprise-commissioned project is to assess the possibility of implementing a pan-European statistical database on mineral resources and reserves in raw materials deposits. As such, it has three main objectives:

• to create a comprehensive directory of where information may be located within the EU28 (and neighbouring) countries;

• to build a web-site so that users may access this listing and find resource data more quickly and easily;

• to develop an action plan for harmonisation of European mineral resources data where this is useful and feasible up to 2020.

Minventory is producing a metadata portal with export functions (MS Excel tables) but no web services. ► EURARE (http://www.eurare.eu/) EURARE is a project funded by the European Commission for the 'Development of a sustainable exploitation scheme for Europe's Rare Earth ore deposits'. The main goal of the EURARE project is to set the basis for the development of a European REE industry that will safeguard the uninterrupted supply of REE raw materials and products crucial for the EU economy industrial sectors, such as automotive, electronics, machinery and chemicals, in a sustainable, economically viable and environmentally friendly way. A task of the EURARE project is to develop an “Integrated Knowledge Management System” (IKMS) that will give access to all available data related to mineral resources containing rare earth elements. ► SNAP-SEE (http://www.snapsee.eu/) The SNAP-SEE project focuses on developing and disseminating tools for aggregates management planning in Southeast Europe (SEE). It builds on the results of the Sustainable Aggregates Resource Management (SARMa) project. The primary objective of the project is to develop a Toolbox for Aggregates Planning to support national/regional, primary and secondary aggregates planning in SEE countries, which will include:

• SNAP-SEE Vision for a transition to integrated, comprehensive sustainable aggregates planning in SEE;

7 of 24

Minerals4EU FP7-NMP2-CA-2013-608921

• Handbook on Capacity Building and Stakeholder Consultation; • Handbook on Data and Analysis Methods; • Aggregates Planning Scheme, containing planning modules that embody the

principles, approaches and action necessary to achieve the goals of the Vision. ► EO-MINERS (http://www.eo-miners.eu/) The purpose of the EC FP7 project EO-MINERS is to use current knowledge and data, along with existing and new technological and scientific earth observation-based methods and tools, to monitor mineral resources exploration and mining from concept to closure and observe, monitor and provide information to manage its impacts on the environment and society. ► EuCoRes (http://ec.europa.eu/energy/coal/eucores/eucores_en.htm

)

The objective of the EuCoRes project is to produce a thorough classification and mapping of coal and coal bed methane in the EU. Next to the formulation of a unified classification and terminology, an extensive geographical database is to be constructed where detailed and georeferenced information of all existing coal deposits in the EU is included. The combined results of the different types of deliverables will serve as reliable starting point for future studies or consultations in this field.

2.2. Review of past projects of interest

► ProMine (http://promine.gtk.fi/ ; http://ptrarc.gtk.fi/ProMine/default.aspx) The purpose of the ProMine project was to enhance overall production chain of minerals and metals in Europe by putting higher quality and added value products on the market. ProMine produced pan-European GIS based resources and modelling system for all potential metallic and non-metallic mineral resources (known and predicted) within EU. Developing modern eco-efficient mineral processing and metal recovery methods and demonstrating the reliability of new (bio)technologies for an ecoefficient production of strategic metals was also a major objective of the project. ProMine produced INSPIRE compliant data, a geospatial data portal, web map services, a web feature service and reports. ► EuroGeoSource (http://www.eurogeosource.eu/ ; http://maps.eurogeosource.eu/) EuroGeoSource is a data portal, which allows Internet access to the aggregated geographical information on geo-energy (oil, gas, coal etc.) and mineral resources (metallic and non-metallic minerals, industrial minerals and construction materials: gravel, sand, ornamental stone etc.), coming from a wide range of sources in a significant coverage area of Europe (ten countries). The project is co-funded by the Competitiveness and Innovation Framework Programme (CIP), under the Policy Support Programme (PSP), Geographic Information Theme.

Minerals4EU FP7-NMP2-CA-2013-608921

The aim of the project is to provide information on oil and gas fields, including prospects and mineral deposits. By developing web services for sharing spatial data between public organizations and authorities (including EC and EU research and policy making institutions), as well as commercial stakeholders, the project’s goal is to enable the creation of value-added services (such as demand-supply modeling) for the sustainable geo-energy and mineral supply of Europe. The practical implementation of the spatial infrastructure for oil and gas and mineral deposit data sets also contributes to themes 20 and 21 of Annex III of the INSPIRE Directive. The EuroGeoSource outputs are intended for the use of the European Commission and its institutions, EU and national geo-energy and mining authorities, oil, gas and mining companies, investment companies, geological surveys, research institutes, universities and the general public. EuroGeoSource produced INSPIRE compliant data, a geospatial data portal, web map services and web feature services. ► SARMa (http://www.sarmaproject.eu/) The purpose of the SARMa project is to develop a common approach to (a) sustainable aggregate resource management (SARM) and (b) sustainable supply mix (SSM) planning, at three scales: regional, national and transnational. Objectives comprise: coordination in managing aggregate resources, increasing the transfer of know-how, and supporting capacity building in firms, government and civil society; develop a unified information infrastructure and common understanding of aggregates based on EU guidelines and directives, including those in protected areas, potential secondary supply, and transnational transportation networks; and to prepare for Regional Centre on SARM & SSM. Activities will connect institutional actors, decision makers, policy implementers, economic sector, quarry operators, civil society, and NGOs through workshops and targeted results. SARMa was considering the development of a GIS web portal for sustainable aggregate management (not found). ► ImpactMIN (http://www.impactmin.eu/) The purpose of ImpactMin was to develop new methods and a toolset for impact monitoring of mining operations using Earth Observations and in-situ data. The objective of ImpactMin project was to collect and process data from designated demonstration sites that represents various environmental and social issues related to mining operations. The analysed data and information then served to conclude how Corporate Social Responsibility and thus the socio-economic aspects of mining are implemented in reality. Beside this, what innovative monitoring techniques and standard procedures can be tailored to measure the environmental impacts of mining activities, thus how quality data and information can be assured. ImpactMIN produced GIS dataset. ► MINEO (http://www2.brgm.fr/mineo/) The objectives of the MINEO project were:

9 of 24

Minerals4EU FP7-NMP2-CA-2013-608921

• To develop advanced methods for the extraction of information and knowledge from Earth Observation data, which will be required in the future in order to provide EC and users (industry, decision-makers) with new and regularly updated thematic layers for environmental database related to mining areas and to develop operational tools for preparing and updating these layers;

• To develop the key components of the decision-making tools and methods to exploit these data and facilitate their use in sustainable information systems to locate and monitor environmental risks related to mining sites and aid the decision processes.

MINEO did not produce a data portal but software and spectral analyses.

2.3. Structured data from Geological Services

As Minerals4EU is dealing with continental primary and secondary (i.e., mining wastes and tailings) mineral resources, continental resources at depth, and marine/offshore resources, a survey on which structured data (i.e., hosted in a database) Geological Surveys will be able to serve has been realized (see annex 1):

1 - To manage and maintain databases related to continental primary resources is for all Surveys a kingly task and, unsurprisingly, it is this task which received the greatest number of positive answers in terms of data availability. Most surveys already set up web feature services (WFS) for serving these data (in-house project or EuroGeoSource project) or will set up rapidly such a service. 2 - Regarding continental secondary resources, it appears that not all Surveys are managing this type of data and answers are thus more 'scattered'. Despite the existence of EC Directives related to Mining Wastes (e.g., http://ec.europa.eu/environment/waste/mining/pdf/Pre_selection_GUIDANCE_FINAL.pdf), it appears that this information is still largely not accessible. For serving these data, two options emerge: (i) some surveys will set up WFS and (ii) the Anthropogenic Concentrations database created in the frame of the ProMine project will –at least temporarily- serve these data for some countries. 3 - As continental primary resources, continental resources at depth data are most of the time managed by Geological Surveys which will set up WFS for serving these data. 4 - The situation is extremely different for marine/offshore resources, as in many countries the survey of these resources depends on specialized institutes and not Geological Surveys. As far as possible, the organizations in charge have been tentatively identified. This task will be pursued in collaboration with the team of the EMODNet-Geology project.

The other objective of this survey was also to evaluate carefully the support the project will have to bring to Geological Surveys for web services implementation (T5.4). Several situations are currently considered (see figure 3), from a total autonomy (point 1 on figure 3) to a limited assistance based on the use of updated (ERML v.2) EuroGeoSource components (point 2 on figure 3) and to a total assistance with the (temporarily) use of the ProMine database (point 3 – right side), ProMine serving in this case data instead of the Survey. This latter option, hopefully not so frequent for continental primary data, will be more widely used for continental secondary resources, for the reasons explained above.

Figure 3: The different ways data held by Geological Surveys can be served

3. New data provided by other work packages Work packages 4 (Minerals statistics) and 6 (Foresight study) will be exchanging data with WP5. Figure 4 is an attempt to describe which types of data are used (input) or produced (output) by these WPs, how they circulate between WPs and/or enter in EU-MKDP and how they will be processed (indexation) and made available for the portal through the Information Factory (see also figure 1, upper right part, for a more general view). This schema also integrates the Minventory project which will provide WP4 with metadata related to the availability of certified reserves/resources datasets at country scale.

Minerals4EU FP7-NMP2-CA-2013-608921

Figure 4: General overview of the data flow within (or around) the EU-MKDP

A first point to mention is that data 'entering in WP4' are not of the same type as those 'entering in WP5' through the harvesting process which feeds the central database ('European MR Data') of the EU-MKDP. WP5 is dealing with records related to single/individual mineral deposits with – depending on the origin and age of data - certified (based on international reporting standards) or non-certified reserves/resources. WP4, for its part, is dealing with data consolidated at country level. It receives this information from Geological Surveys, EUROSTAT and other agencies. Part of the information is also coming through the well-established BGS-NERC network. It is foreseen that the EU-MKDP will be able in a near future to provide WP4 with such data as the deposit production (cumulated or per year), the reserves and resources (with dates and reporting code used…) are parts ('features') of the international ERML v.2 data model used to set up web services feeding the central database. Dedicated services will be developed on top of this base, within the Information factory, in order to allow compiling yearly or cumulated production, reserves and resources, per commodity at country scale. This will also apply to data related to secondary mineral resources and to exploration. WP4 will also compile new data2

2 The team at BGS already collects production data from all countries of the world, and trade data for 35 European countries. These are published by BGS in two annual books: “World Mineral production” and

related to reserves and resources, secondary resources and exploration (an innovation of the New European Minerals Yearbook) and will make an

Minerals4EU FP7-NMP2-CA-2013-608921

assessment of the steps required to harmonise them. If this harmonisation is possible within the time-frame of the project, these data will then enter in the EU-MKDP (figure 4 - box on the right side of the diagram). Depending on their number, these data may be stored in a dedicated database 'MR Info', before indexation and entering in the Information factory. WP4 will also provide the EU-MKDP with syntheses in PDF format (such as the New European Minerals Yearbook) and statistics in the form of graph charts, time-series (Excel format or images), accompanied by simplified metadata/keywords, and which will be indexed and entered in the system, always using the bow on the right side of the diagram. WP6 will receive information from Geological Surveys, universities, research institutes and non-governmental organizations. The contribution of WP6 towards WP5 will be of the same nature as WP4. It is also noteworthy that WP4 will also provide WP6 directly with time-series (up to 10 years back) useful to set up long term trends and foresights.

4. The metadata system The metadata system must enable standardized description and search of all identified data on mineral resources and related topics. In order to provide an efficient way to make the data discoverable, the decision was taken not to develop a completely new tool, but to modify the OneGeology-Europe (1G-E) Catalogue (MIcKA). This tool is fully compliant with international standards and also supports the distributed system of metadata administration. The analysis presented above reflects that only digital and structured information (spatial datasets or dataset series and spatial data services - WMS, WFS) will be described by metadata in the project metadata catalogue.

4.1. Strategy for the Minerals4EU metadata architecture

During the WP5 workshop (November 26th, 2013, Paris), the discussion about the Minerals4EU metadata architecture concerned two possible strategies: a distributed system based on the INSPIRE metadata profile (INSPIRE strategy) or a project-specific system (1G-E strategy). The already existing INSPIRE compliant metadata may be available and possibly harvested from the European/national geoportals. The advantage of the distributed system is the possibility to reuse already existing metadata from the European/national systems. This implies less additional work for the data providers “European Mineral Statistics” (http://www.bgs.ac.uk/mineralsuk/statistics/europeanStatistics.html). The production and trade data will be the same in the BGS publications and the new European Minerals Yearbook, but the Yearbook will also contain resources/reserves, secondary materials and exploration data (where possible). Taken from the Minutes of the WP Leader Meeting, Brussels, November 21st, 2013.

13 of 24

Minerals4EU FP7-NMP2-CA-2013-608921

as they should already be providing INSPIRE compliant metadata for their datasets. However, they would have to comply with the project requirements, i.e. to add English translations (if not existent) and project-specific keywords from a controlled vocabulary. The disadvantages of this strategy are the reduced possibilities of searching (no additional detailed project-specific description is available) and the risk of lower performance implied from the distributed system. The project-specific system such as the 1G-E metadata catalogue gives the opportunity for more detailed description of metadata, the use of specific code lists and content templates, and for reaching a high degree of multilinguality. The disadvantage is that the system must be manually maintained and requires more effort from the data providers (duplicating and enriching the original metadata records, translations of multilingual parts). The possibilities how metadata can be inserted and maintained in the catalogue are presented in Figure 5 and described in the following paragraph as 3 possible scenarios.

Figure 5: Possible access to the metadata catalogue

Scenario 1: Participant has no metadata catalogue Solution: All metadata will be created in the Minerals4EU metadata catalogue editor with the possibility to download / harvest them to participant’s own metadata catalogue / repository for future use. Scenario 2: Participant has own metadata catalogue, but metadata are not compatible with Minerals4EU profile/rules and the participant does not want to change them in his catalogue. Solution: Metadata will be harvested only once from the participant´s catalogue to the Minerals4EU catalogue (initial filling), then edited in the Minerals4EU catalogue. It is possible to harvest / download edited metadata back by the participant.

14 of 24

Minerals4EU FP7-NMP2-CA-2013-608921

Possible problems: There is no exact rule how to distinguish metadata records that are to be harvested to Minerals4EU catalogue (filter conditions). Moreover, this solution results in two different versions of metadata in two repositories. Scenario 3: Participant has own metadata catalogue and metadata are compatible with Minerals4EU profile/rules or will be edited to be compatible by the project end or a defined deadline Solution: Metadata will be regularly harvested from this node to the Minerals4EU catalogue. It will ensure synchronizing between both metadata versions.

Service metadata will contain links to original dataset metadata as reference (OperatesOn element). If these are not available on-line, the datasets metadata should be stored in the Minerals4EU catalogue. Both the scenario 1 and 3 can be possibly incorporated in the proposed metadata system. Scenario 2 is also possible, though not recommended.

4.2. Metadata profile

Based on the discussion above, the decision has been taken to define and implement a fully ISO 19115 and INSPIRE compliant metadata profile for Datasets and dataset series and ISO 19119 and INSPIRE compliant metadata profile for Spatial data services (WMS, WFS). The profile will be compliant with the technical guidelines for metadata from 2013-10-29 and should include additional elements from the INSPIRE Data Specification on Mineral Resources – Technical Guidelines, v.3.0 from 10.12.2013. Metadata elements for interoperability:

coordinate reference system (mandatory), temporal reference system, encoding (mandatory), topological consistency, character encoding, spatial representation type (mandatory).

Theme-specific metadata elements from the Mineral resources DS – optional:

maintenance information (mandatory maintenanceAndUpdateFrequency), conceptual consistency, domain consistency.

4.3. Multilinguality

The fully multilingual aspect is not of a key importance for Minerals4EU, but the metadata records should be at least bilingual (national language + English) for title, abstract and keywords. Translations of the OneGeology-Europe keywords will be filled automatically from

15 of 24

Minerals4EU FP7-NMP2-CA-2013-608921

the controlled vocabulary. For every record, the use of at least one keyword from the 1G-E/Mminerals4EU thesaurus will be mandatory. English should be set as the “secondary” language in the metadata. Bilingual metadata snippet example: <gmd:title xsi:type="gmd:PT_FreeText_PropertyType"> <gco:CharacterString>Rudní ložiska ČR</gco:CharacterString> <gmd:PT_FreeText> <gmd:textGroup> <gmd:LocalisedCharacterString locale="#locale-eng">CZ Ore deposits</gmd:LocalisedCharacterString> </gmd:textGroup> </gmd:PT_FreeText> </gmd:title>

4.4. Code lists, keywords

The multilingual database (1G-E/Minerals4EU Thesaurus) of relevant keywords will be developed as an extension to the OneGeology-Europe thesaurus. The vocabulary should be compliant with GEMET API. Data Specification on Mineral Resources and Technical Guidelines code lists should be taken into account. This will help to describe mineral resources data in detail. Metadata records must contain at least one keyword from this thesaurus. A proposal of the 1G-E thesaurus extension is in Annex 2. The vocabulary will be exposed as a web service. The keyword should be coded as URI according to the latest technical INSPIRE Metadata Technical Guidelines (October 2013). The “M4EU” keyword ensures exact identification of Minerals4EU metadata records, particularly for harvesting purposes, when metadata are maintained in original participant’s metadata catalogues. Keywords with URI representation example: <gmd:MD_Keywords> <gmd:keyword> <gco:CharacterString>Minerals4EU</gco:CharacterString> </gmd:keyword> <gmd:keyword> <gco:CharacterString>http://m4eu.eu/concept/1</gco:CharacterString> </gmd:keyword> </gmd:MD_Keywords>

Minerals4EU FP7-NMP2-CA-2013-608921

4.5. Metadata system and technology

MIcKA is an already operating technology for metadata management, developed during the OneGeology-Europe project. It contains tools for editing and management of metadata for spatial datasets and spatial data services. It includes the search on the Internet and download of metadata XML files to local computer. MIcKA is compatible with the obligatory standards for European SDI building (INSPIRE). Therefore, it is ready to be connected with other nodes of prepared network of metadata catalogues. The proposed version of the system, amended for Minerals4EU purposes, will consist of the following components: Metadata Catalogue - searching tools (GEMET, 1G-E/M4EU web services) Metadata Editor - tool for creating, updating and maintaining the metadata records Catalogue Service for Web (CS-W 2.0.2.) - service for online integration of the metadata records with the project portal or other portals (e.g. INSPIRE geoportal, National geoportals, M4EU geoportal, 1G-E geoportal, other project-specific geoportals etc.) Support for ISO 19115 (datasets)/19119 (services)/19139 (XML)/15836 (Dublin Core) Support and validation of INSPIRE metadata profile

4.6. Sustainability of the system

In order to implement the system successfully, the support involving the provision of the amended metadata cookbook and the helpdesk advisory service for geological surveys will be necessary. Training can be provided if requested by the consortium. The responsibility for metadata creation is upon the participants - data providers. The responsibility for metadata system maintenance can possibly follow the already functioning model of Service Level Agreement between EGS and CGS. For maintenance of such a system, a functional personal network across participating organizations in Europe is crucial.
