  1. 1. Open Geospatial Consortium: Open Standards and Participatory ProcessGI2012-X-Border-OpenDataPolicies-Forum Dresden, GERMANY, 18./19. May 2012 Athina Trakas Open Geospatial Consortium Director European Services
  2. 2. Agenda A few words about OGC OGC Programs and Processes Development of an OGC Standard Communities and Participation © 2012 Open Geospatial Consortium
  3. 3. Before we start...Q: What is the OGCs position on "Open Data"? - OGC embraces open data as well as other models for datadistribution and access. The OGC standards framework must support abroad range of policy positions on the access to and distribution ofgeospatial data, and we are supportive of all models for open access,licensed data, secure distribution, etc. Policies on access and distributionof geospatial and other forms of data are constantly in flux. Data setsrestricted for distribution by security and/or pricing / licensing, may beopened up for free access at another time. Changing market forces andorganizational policies determine the rules for data access and distribution.Open standards, including those of the OGC, support the full range ofbusiness models, and a common open standards framework is vital tothe overall geospatial data marketplace. © 2012 Open Geospatial Consortium
  4. 4. A few words about OGC
  5. 5. Standards and InteroperabilityAvailability of geo data is crucial for the administration, businesses and citizens alike. But how to share data? Key factor for accessibility is standardisation. It is the definition of common interfaces to enable interoperability. © 2012 Open Geospatial Consortium
  6. 6. Interoperability Issues ● „We cant share maps on the Web.“ ● „We cant deliver data to different systems easily.“ ● „We dont have a common language to speak about our geospatial data or our services.“ ● „We cant find and pull together data from our automated sensors.“ © 2012 Open Geospatial Consortium
  7. 7. So what does OGC do? The Vision Achieve the full societal, economic and scientific benefits of integrating location resources into commercial, institutional and organisational processes worldwide. The Mission To serve as a global forum forand lead the development, promotion and harmonization of open and freely available geospatial standards. © 2012 Open Geospatial Consortium

  16. 16. What is an OGC Standard?• A document, established by consensus, approved by the OGC membership (balance of interest, all members have an equal vote)• Provides, rules, guidelines or characteristics• Implementable in software• Open standards does not mean open source software (Free Software). OGC/OSGeo Paper on Open Source Software and Open Standards:• OGC standards are „People want the government Open Standards to be transparent, so why – Freely and publicly available shouldnt the technology be?” – No license fees Jim Willis, Director of e-Government at – Vendor neutral theRhode Island Secretary of State Office © 2012 Open Geospatial Consortium
  17. 17. Why Open Standards?● Prevents a single, self-interested party from controlling a standard „What OGC brings to• Lower systems and life the table is…everyone has confidence we cycle costs won’t take advantage of the format or change it• Encourage market competition in a way that will harm – Choose based on functionality anyone” desired Michael Weiss-Malik, – Avoid “lock in” to a proprietary Google KML product architecture manager• Stimulates innovation beyond the standard by companies that seek to differentiate themselves.

  18. 18. Standards are like parachutes: they work best when theyre open. Mary Mc Rae, OASIS* * “Minds, like parachutes, function better when open, but, like fists,they strike harder when closed.” — L.E. Modesitt, Jr., American Author (1943 -- ) © 2012 Open Geospatial Consortium

Positive Feedback / InterestInitiate an Interoperability Start a Domain WorkingProgram initiative: Group (DWG):● Special pre-requirements ● Special pre-requirements needed needed (a certain number of OGC member, email to the● Results: e.g. an Engineering Technical Committee etc.) Report ● Results: charter, mailing list,● With enough interest / Wiki, timeframe (e.g. for support by OGC members, teleconferences, meetings, development of an working expected results etc.) group © 2012 Open Geospatial Consortium
  43. 43. How is an OGC standard developed? 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 givenperiod of time (usually 30d ays):● 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 © 2012 Open Geospatial Consortium
  44. 44. Role of the OGC and OGC staff● Community forum● Comprehensive communications infrastructure● An agreed upon consensus process for defining, testing, documenting and approving standards● Support the process formally, has the overview of the “standards- family” and relevant activities in other organisations (alliance partners)● Staff knowledge, expertise and support to work with the members to facilitate the consensus process that leads to approved and adopted standards © 2012 Open Geospatial Consortium
