2 Who is Athina? Athina works in the field of GIS since 1998 after finishing university with a diploma in Geography. She worked with CCGIS and WhereGroup being responsible for Business Development and International Outreach for Free and Open Source GIS and standards. Since 2009 she is OGC's Director for European Services. Athina is contact person for OGC in Europe, responsible for the Consortiums OGC activities and networking, like planning and managing of OGC recruitment, connecting with European stakeholder organisations and members. Athina is charter member of OSGeo since Additionally she is charter member of the Open Source Geospatial Foundation (OSGeo) since Open Geospatial Consortium 2

7 How is an OGC standard developed? Issue / problem 2013 Open Geospatial Consortium 7

8 How is an OGC standard developed? Issue / problem 2013 Open Geospatial Consortium 8

9 How is an OGC standard developed? Issue / problem Tell the relevant working group Send to the TC-mailing list Talk to OGC members and/or staff Communicate! 2013 Open Geospatial Consortium 9

10 How is an OGC standard developed? Initiate an Interoperability Program initiative: Special pre-requirements needed Results: e.g. an Engineering Report With enough interest / support by OGC members, a working group can be established Positive Feedback / Interest Start a Domain Working Group (DWG): Special pre-requirements needed (a certain number of OGC members, to the Technical Committee etc.) Results: charter, mailing list, Wiki, timeframe (e.g. for teleconferences, meetings, expected results etc.) 2013 Open Geospatial Consortium 10

11 How is an OGC standard developed? Results achieved in the DWG/SWG may be: A Discussion Paper or a Candidate Standard document is being developed It will be reviewed by the OGC Architecture Board (OAB) and the Technical Committee (TC). Once an OGC document is published (by vote of the SWG), everyone who is interested can comment on it within a given period of time (usually 30 days): Requests to the document need to be answered by the relevant SWG Changes and comments need to be included (SWG works the comments) SWG votes to release to the TC for an adoption vote, vote happens New approved standard published 2013 Open Geospatial Consortium 11

12 OGC Domain & Standards Working Groups Standards Program (SP): (i) Domain Working Groups: Forum for discussion and documentation of interoperability requirements for a given information or user community, Informal presentations and discussions about the market use of adopted OGC Standards ( (ii) Standards Working Groups: Edit and approve a candidate standard for public comment, Consider official Change Request Proposals to an existing OGC Standard and make changes to the standard as necessary ( Open Geospatial Consortium 12

15 OGC MetOceans DWG: example for cooperation (Cross Domain Modeling) The OGC MetOcean DWG provides the forum for development of a harmonized data model for meteorology. Slides from presentation given by Jeremy Tandy at the Toulouse OGC TC Meeting (Sept. 2010) Main stakeholders in this activity comprise: WMO, INSPIRE (TWG Atmospheric Conditions & Meteorologica Features), aviation and earth science community Open Geospatial Consortium 15

16 INSPIRE technical architecture INSPIRE Discovery service: OGC Catalogue Service for the Web (CSW) Query language: OGC Filter Encoding INSPIRE View service: ISO : WMS (Web Map Service) 1.3 (extensions) INSPIRE Download service: Pre-defined data sets => standard Internet protocols (like FTP) Direct access data with queries Web Feature Service: OGC WFS / ISO Filter Encoding: OGC Filter Encoding / ISO INSPIRE Coordinate Transformation service: An Application Profile of the Web Processing service (WPS) based on the Web Coordinate Transformation Service (WCTS) OGC Open Geospatial Consortium, 2011 Making Location Count... 16

17 INSPIRE and OGC Standards Market Report on open Standards in INPSIRE provide examples activities underway around INSPIRE based on international standards, highlight overlap between OGC and ISO standards (e.g. ISO 19115) This purpose of this special OGC market report is to provide INSPIRE stakeholders with an overview of OGC, CEN and ISO standards in INSPIRE and to provide clarification of the Implementing Rules with respect to standards. The report highlights the fact that INSPIRE has some elements that are legally binding and other elements that are not. INSPIRE Implementing Rules are legally binding, but they do not specify particular standards or technologies. Technical Guidance documents accompanying the Implementing Rules provide the implementation details but they are not legally binding documents. Technical Guidance documents reference OGC, ISO and other standards Open Geospatial Consortium 17

18 OGC and INSPIRE We encourage members and the public to make suggestions for improving OGC standards, or for developing alternatives to better fit users application requirements, including to support INSPIRE. Please note: existence of INSPIRE s due date does not by itself speed up processing feature requests and change requests within OGC. It is up to the submitter to champion the requests or find proxies to champion the changes! If you don t shepherd your request, who will? And if someone else does, are you sure they are looking out for your interests? 2013 Open Geospatial Consortium 18

22 OGC Change Request

23 Submitting a Change Request to the OGC All technical development underlies a lot of changes. Standards rely heavily on dependencies. Instead of reinventing the wheel again and again, standards reference other standards. Therefore any change in a standard is bound to disrupt other development, especially in the underlying layers. Still, sometimes there is a need for changes, to make these known they have to be submitted as a Change Request. This section will highlight the steps involved.

24 Collaboration and Cooperation The CEN/TC 287 workshop on best practice for National Spatial Data Infrastructures (NSDIs) convened in Saint-Denis, Paris, France on 1 March This provided an excellent venue and opportunity for organizational representatives of CEN/TC 287, ISO/TC 211 and OGC to discuss ways in which coordination between these standards bodies can be improved to better address European and international standards requirements. Discussions also included representatives from participating user communities, and led to general agreement for closer, more formal cooperation between OGC and CEN/TC 287, as well as agreement to consider continued improvements in OGC and ISO/TC 211 coordination. Emphasis was also placed on the testing of standards for viability, fulfillment of purpose, ease of implementation and improvements in interoperability. The mantra "test early, test often" was reflective of this need. These three organizations will be cooperatively exploring the adoption of a common Change Request / Requirements registry, and will be examining ways in which adopted standards schema can be managed more effectively and efficiently across these organizations. The requirements process is also an effort to make the standards process more transparent and more responsive to community needs. All requirements and change requests will be gathered in an open forum visible to the public. All parties agreed that continued exploration of process improvements would be valuable to the community, with particular focus on improved coordination, reduction in duplication of effort, and streamlining of standards coordination processes Open Geospatial Consortium 24

29 OSGeo Incubation

30 OSGeo Incubation The Open Source Geospatial Foundation has setup a rigorous quality assessment. Any project wishing to become endorsed by OSGeo has to go through this process and prove that it follows the best practices laid out by OSGeo. This quality assurance ensures that projects are managed and run in a sustainable way and that users can rely on it's longevity Open Geospatial Consortium 30
