GOAL

See if EDMED (data base decription), Cruise Summary Report (Roscop) could be described by :

XML in compliance with ISO-19115

3

lfremer


APPROACH

List all the needed information of an EDMED form, a CSR (ROSCOP form from ICES WEB site)Look up a standard definition in ISO-19115 for each information Define an XML tag in compliance with ISO-19115 for each information

4

lfremer


Results on EDMED mapping

Almost all the EDMED information has been mapped to ISO-19115 Exception 3 fields not compatible with ISO

CENTER HOST optional field (Language dependant)CURRENCY DATE and REVISION DATE cannot be applied to DATA CENTRE and to CONTACT. Date can only be linked to the data base description.

Deliverables

XML Schema

Generated from the ISO-19115 DTD using XMLSPY Original standard schema has been restricted to

the tags needed by EDMED the mandatory tags of ISO (tpCat = topic Category, …)

Updating EDMED entries

257 EDMED XML files transmitted to BODC very recentlyCurrently 226 French EDMED descriptions on the SEA-SEARCH WEB SITE31 new entries and updates on some previous ones

Results on CSR mapping (1)

All the information has been mapped to ISO-19115 and GML:

Last version of ISO-19115 allows the description of samples and measurements and of ship information

•Tag <aggrInfo> provides aggregate dataset information

Results on CSR mapping (2)

Port of departure and return fit into Keywords : departure_place, arrival_placeMARSDEN squares and Ocean areas (IHB) fit into ISO-19115<dataExt>

<geoEle>For other geographic information, GML standards has been used

14

lfremer


Geographic Markup Language

GML is consistent with existing OGC (OpenGIS Consortium)

GML is an XML encoding for geographic information, including both the spatial and non-spatial properties of geographic features

Next step

Prepare the XML example fileDistribute the Version 0 to all partners who volunteer to comment about it Prepare a version 1.0 for the CSR

Last checks and take into account the partner’s comments

available by the middle of July ?

Small modification of EDMED schema

Compatibility between tags for EDMED and tags for CSRMapping of CSR has had some influence on the EDMED previous schema2 very small modifications

Comment about the date format : ISO-8601Tag <identAuth> added under <GeoId>

• to identify the author of the used code list : IHB in the case of EDMED

Version 1.01To be distributed

CDI and ISO-19115

Common Data Index also compatible to ISO-19115

In the frame of an Internal IFREMER project, a data index has been developpedNeed some adjustments and improvements to be fully compatible with the Sea-Search CDI
