1.    IUGS-OGC GeoSciML v4.0 SWG


2.    Purpose of this Standards Working Group

The purpose of this Standards Working Group is to progress the GeoSciML GML data model and application schema for geoscience information interchange to the state of an adopted standard. This will be achieved by processing comments received during the public comment period and ensuring that the standard is consistent with the OGC business plan.

3.    Scope of Work

This SWG will focus on adapting the GeoSciML v3 GML schema to an OGC modular specification and XML implementation and adoption of an abstract specification and XML implementation specification as OGC standards. Work will be based on the GeoSciML v3 model as documented at
3.1        What is Out of Scope?
This SWG will focus only on processing comments received during the 30 day public comment period. Any Change Requests which are not compatible with current implementations of GeoSciML v3 are out of scope. All change requests will be retained for consideration for later versions of the standard.
3.2        Specific Contribution of Existing Work as a Starting Point
The starting point for the work will be the GeoSciML v3.0 model as documented at   Preliminary draft OGC specifications for the abstract model and XML implementation will be sent out for public comment following any edits needed to meet RFC requirements.
3.3        Determination of SWG Completion
The work of the GeoSciML 4.0 SWG will be complete when:

  1. All comments submitted during the 30 day public comment period have been dealt with to the satisfaction of the SWG.


  1. The SWG approves the OGC GeoSciML v4 Abstract Specification,  Abstract Test Suite, XML Implementation Specification, and XML Implementation Abstract Test Suite for submission to the TC for approval as an adopted standard.


  1. The candidate standard has been approved by the OGC Technical and Planning Committees as an Adopted OGC standard.

4.    Description of Deliverables

The following deliverables will result from the work of this SWG:

  • An annotated list of all comments submitted during the 30 day public comment period, including the comment, submitter, rationale, comment type/priority, and the response of the SWG.
  • A final version of the GeoSciML 4.0 documents for submission to the TC. These will include an Abstract Specification, XML Implementation specification, and associated abstract test suites.

In recognition of the amount of effort from a number of groups that has gone into developing GeoSciML v3 to its current state, the SWG should conclude its activities no later than Q1 2014. As such the following schedule of activities is planned:

  • SWG startup. 2013 January.
  • OAB/ONA RFC review; SWG prepares candidate standard for vote for public release. 2013 March
  • SWG votes to release GeoSciML 4.0 for public comment. 2013 April
  • OGC staff develops PR and announces availability for public comment. 2013 April
  • 30-day public comment period. 2013 April - 2013 May
  • SWG collects and collates comments into a single document. 2013 June
  • SWG discusses and votes on comments and makes resulting edits towards final GeoSciML 4.0 candidate standard. 2013 September
  • SWG votes to approve release of GeoSciML 4.0 candidate standard for approval as an OGC adopted standard. 2013 September
  • 60 day IPR review period and associated TC e-vote to approve GeoSciML 4.0 candidate standard as an OGC adopted standard. 2013 October – 2013 November


5.    IPR Policy for this SWG

The Intellectual Property Rights for this SWG are governed under Item 4 of the Memorandum of Understanding between OGC and IUGS Commission for the Application and Management of Geoscience Information (CGI).

6.    Anticipated Participants

The SWG will consist of interested parties from Geological Surveys, Academic institutions, and commercial and government organizations that utilize geoscience information. Members of the current IUGS CGI Interoperability Working Group are expected to continue involvement.

7.    Other Informative Remarks about this SWG

a. Similar or Applicable Standards Work (OGC and Elsewhere).
b. Details of the First Meeting
The first meeting of the SWG will be held at the OGC TC meeting at Redlands, USA, 14-18 January 2013.  Call-in information will be provided to the SWG email list and on the portal calendar in advance of the meeting.c. Projected On-going Meeting Schedule
The work of the SWG will be carried out primarily by email, with conference calls as required.   Face-to-face meetings with optional attendance via conference call will coincide with OGC TC quarterly meetings. d. Supporters of the ProposalThe following people support this proposal and are committed to the Charter and projected meeting schedule. These members are known as SWG Founding or Charter members. Once the SWG is officially activated, this group is immediately “opted-into” the SWG and have voting rights from the first day the SWG is officially formed. Extend the table as necessary.
