Objectives

5

This study has been prepared in the context of the Interoperability for European Public Administrations (ISA) Programme and, in particular A Reusable INSPIRE Reference Platform (ARE3NA, ISA Action 1.17)

Connecting Geospatial DataThis study should provide:

1.Shared evidence about the current status in Europe of linked (geospatial) data related to INSPIRE.2.An initial common/agreed methodology and guidelines towards RDF encodings for INSPIRE3.Recommendations for how location PIDs could be governed for INSPIRE and other relevant activities.


Scope

6

Resources on the web that contain data about real-world things

Real-world things such as a river basin, train station, a country, etc.

Linked Data Principles

1) Use URIs as names for things2) Use HTTP URIs, so that people can look up those names3) When someone looks up a URI, useful information should be provided, using the standards (RDF, SPARQL)4) Include links to other URIs, so that they can discover more things

<<assign>> <<assign>>

<<include>>

PID = A persistent identifier (PI) is a long-lasting reference to a digital object—a single file or set of files. Noted persistent identifier systems include: Archival Resource Keys (ARKs), Digital Object Identifiers (DOIs), Persistent Uniform Resource Locators (PURLs), Uniform Resource Names (URNs), and Extensible Resource Identifiers (XRIs)

Governance refers to the control and the steering of the decisions on PIDs

Operations is about the processes and tools needed to run PIDs

Financing is about the resources needed for the operations and the architectural updates

Architecture corresponds to a formal specifications around PIDs

Governance

17

Preliminary conclusions

Based on available data analyzed until now:

1)Policy is often associated with URI design patterns and the management of domains. However, there is definitely more than these two elements.

2)When a policy exists it isn’t always well formalized depending on the size and organizational structure.

3)There seem to be no examples of PID organizational structures in the context of INSPIRE and in e-Government.

4)There is a lot of theoretical work about the “technical side” of persistent identifiers, often associated with linked data

5)Lack of a holistic picture that integrates the several GOFA dimensions.

Barriers


1)PIDs governance is an inherently complex topic given the way that “ICT governance and management” is done in the different Member States

2)There is “no silver bullet” for PID governance

PIDs PolicyDefines what

and how can be assigned a PDI

ValidationValidates the

format, location and the uniqueness of

PIDs

RegistrationCreates and registers

PIDs

Redirection Uses persistent PIDs

to redirect to the desired Web

resource

Long Term Preservation

Archives fullback copies of “dead”

resources

Business CaseJustifies the investment in persistent identifiers

Cost ModelDefines the allocation of costs and charges associated with the provision of persistent PIDs.

PIDs Organisational structureDefines who has the authority and control (planning, monitoring and enforcement) over the management of PIDs

Service ModelDescribes the set of services that will benefit from the use of persistent PIDs, this encompasses both data and metadata about services

1)There are no formalized business cases for PIDs – we believe that the interest in linked data is sometimes enough:

e.g. John Sheridan, Head of Legislation Services “A business case for using linked data would like making a business case for using electricity.”

•There seems to be no cost model for PIDs. For Linked Data or the implementation of INSPIRE, when they can be found, they are very different from one case to the other. Below are a few examples:

Development costs, Maintenance costs, Promotion costs – Linked Data

Operating costs of the IT infrastructure, Production of interoperability Business model for the implementation of INSPIRE, IT structure Processing of spatial data, Personnel – INSPIRE Germany

Barriers

1) No clear understanding on the investment needed to set up PIDs.

1)The domain owner is implicitly considered to be responsible for registration and validation

2)There is little discussion about long term preservation and most papers mention 303 Redirection

3)There is little discussion about validation of PIDs (it is much more about standardization and very little about control)

Most work has been done in this area.

1)Most referenced work is the 10 Rules for Persistent URI and Designing URI sets for UK Public Sector

2)There is no EU agreed policy for PIDs for centrally managed, shared resources

3)Several guidelines have been put forward for the URI persistence ( W3C - RFC2616., UK - Designing URI sets for UK Public Sector, ISA), but currently these are just recommendations and not always aligned

Barriers

1) Control and validation are as important as standardization but often overlooked.
