3 A few words about OGC

4 Standards and Interoperability Availability 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 Open Geospatial Consortium 4

5 Interoperability Issues We can't share maps on the Web. We can't deliver data to different systems easily. We don't have a common language to speak about our geospatial data or our services. We can't find and pull together data from our automated sensors Open Geospatial Consortium 5

6 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 for and lead the development, promotion and harmonization of open and freely available geospatial standards Open Geospatial Consortium 6

7 What is the OGC? more videos on OGC's Youtube Channel: Open Geospatial Consortium 7

8 OGC at a glance Founded in 1994, not for profit, consensus based and voluntary Over 450+ member organisations (industry, government, academia) (May 2012) 21 staff members 25+ adopted OGC Standards (some are ISO Standards) Several hundred software products, implementing OGC Standards Broad user community worldwide, many policy positions for NSDI based on OGC standards Cooperation with other standards organisations and foundations, ISO/TC 211, OSGeo, W3C, OASIS and others Open Geospatial Consortium 8

11 Cross-Boundary Information Sharing Continues to be one of our biggest challenges! Source: Source: The ability to access, fuse and apply diverse data sources is critical to situational awareness 2012 Open Geospatial Consortium 11

12 Improving Knowledge Sharing and Transfer We are addressing critical issues, that need cooperation: Growth in urban centers and coastal areas Climate Change, Environmental Monitoring Water Resource availability and quality Emergency planning, preparedness & response Aviation Safety...and many more Open Geospatial Consortium 12

13 Major OGC Standards Some examples Web Map Servers (WMS) Web Feature Servers (WFS) Web Coverage Servers (WCS) Web Feature Server Web Coverage Server Web Map Server With OGC web services, a user can dynamically access that data, directly from the authoritative data source, using a variety of tools. As well as the: OGC KML (formerly Keyhole Markup Language) Web Map Context (WMC) Geography Markup Language (GML) Just as is the dial tone of the World Wide Web, and html / xml are the standard encodings, the geospatial web is enabled by OGC standards Open Geospatial Consortium 13

14 Standards Development is not easy! Requires understanding of differences Requires cooperation on a global basis Requires consensus by many organizations Requires give and take Requires certified, repeatable process 2012 Open Geospatial Consortium 14

17 Roots and background GRASS Interagency Steering Commitee 1994 Open GRASS Foundation (OGF) Open GIS Consortium (OGC) Open Geospatial Consortium (OGC) Source: Markus Neteler See also: Common areas of work between OGC and OSGeo: OGC Standards (e.g. OGC Web Map Service, Web Map Context, Style Layer Descriptor etc.), GeoRSS The FOSSGIS community developed and contributed numerous reference implementations to existing OGC standards Open Geospatial Consortium 17

18 Open Source Software Development Open Source is a development methodology that aims at making all processes transparent. One central paradigm is to "Publish Early and Release Often". This will help to "build"[1] a community of high interaction. Development is coordinated through roles. Roles must be managed by a clear governance model. Good Open Source projects are highly organized and trunk commit access is restricted to well known developers. Public code repositories, bug and issue trackers, mailing lists,etc. are essential to "grow" [1] professional communities. [1] communities cannot be "built", "managed" or "grown". They need to grow by themselves. Open Source project management can only facilitate and enable communities. Slide provided by Arnulf Christl - President of OSGeo 2012 Open Geospatial Consortium 18

19 Open Standards Development Open Standards follow a development methodology that aims at making processes transparent. One central paradigm is to "Publish Early and Release Often". This will help to "build"[1] a community of high interaction. Development is coordinated through roles. Roles must be managed by a clear governance model. Good Open Standards are highly organized and publishing is managed through a trusted organization. Public schema repositories, mailing lists etc. are essential to "grow"[1] professional communities. Slide provided by Arnulf Christl - President of OSGeo 2012 Open Geospatial Consortium 19

20 MoU OGC The OGC is a not-for-profit organization founded in 1994, and comprised of industry, government and academic members dedicated to advancing interoperability among IT systems that process geo-referenced information. The OSGeo is a not-for-profit organization founded in 2006 whose mission is to support and promote the collaborative development of open source geospatial technologies and data. The Parties wish to make sure that open standards are made freely available to the global public; unencumbered by patents or other Intellectual Property claims that may diminish their usefulness. The Parties wish to memorialize their understanding regarding certain joint activities in which they plan to engage. (Excerpt from the Memorandum of Understanding) Slide provided by Arnulf Christl 2012 Open Geospatial Consortium 20

21 Content of the MoU OGC Additional reference implementations of OGC standards; Defining new requirements and use cases for extensions to existing OGC standards as well as new OGC standards; Having a community of practice that can very quickly implement and test any candidate OGC standard and provide implementation experience feedback; A birthing place for new candidate standards that have been developed outside the OGC process but are submitted into the OGC standards track; Helping us define how to implement OGC standards in a variety of architectural patterns, such as REST (ROA) and SOA.

22 How does OGC work? Programs and Processes

23 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 Open Standards Freely and publicly available No license fees Vendor neutral People want the government to be transparent, so why shouldn't the technology be? Jim Willis, Director of e-government at therhode Island Secretary of State Office 2012 Open Geospatial Consortium 23

24 Why Open Standards? Prevents a single, self-interested party from controlling a standard Lower systems and life cycle costs Encourage market competition Choose based on functionality desired Avoid lock in to a proprietary architecture What OGC brings to the table is everyone has confidence we won t take advantage of the format or change it in a way that will harm anyone Michael Weiss-Malik, Google KML product manager Stimulates innovation beyond the standard by companies that seek to differentiate themselves.

25 Standards are like parachutes: they work best when they're 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 ( ) 2012 Open Geospatial Consortium 25

38 The OGC and its Interoperability Program OGC Interoperability Program Introduction more videos on OGC's YouTube Channel: Open Geospatial Consortium 38

39 IP - Emphasis on Testing and Validation Testbeds, Pilots and Experiments Participants work with sponsors to define and/or refine standards to solve a given interoperability problem. Joint actions by technology providers and users Driven by user community scenarios Produce: Tested and validated draft standards Industry technology implementations Architectural recommendations Live demonstrations to validate utility of standards in user context Over 50 initiatives have been successfully completed since Most OGC standards are advanced through this process. OGC staff manages the entire process with policies and procedures proven to produce results Open Geospatial Consortium 39

40 Benefits The AIP-3 Disaster Management Reference Scenario is a key contribution, helping participants to define efficient procedures and related GEOSS services to provide the right response at the right time to an emergency situation. The scenario demonstrates information flows involved in providing real-time updates to an evacuation plan during a flood disaster." Arnaud Cauchy of Spot Image, an EADS Astrium company, explained, " ( ) GEOSS Architecture Implementation Pilot (AIP) 3 Navin Vembar, Aeronautical Information Management (AIM) Acquisition Lead, FAA, reported, "The ( ) pilot proves that OGC Web Services can be used in concert with domain-specific information exchange standards to satisfy the operational needs of a wide variety of users. The use of the standards means that all of the stakeholders' costs decrease while the benefits of the communication are realized quickly." OGC Aviation Information Brochure Dave Wesloh, NGA: "We are very much a supporter of the OGC Interoperability Program. It provides us with a opportunity to set our requirements out in the community."

42 Development of an OGC Standard

43 How is an OGC standard developed? Issue / problem 2012 Open Geospatial Consortium 43

44 How is an OGC standard developed? Issue / problem 2012 Open Geospatial Consortium 44

45 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! 2012 Open Geospatial Consortium 45

46 How is an OGC standard developed? Positive Feedback / Interest Initiate an Interoperability Program initiative: Special pre-requirements needed Start a Domain Working Group (DWG): Results: e.g. an Engineering Report With enough interest / support by OGC members, development of an working group Special pre-requirements needed (a certain number of OGC member, to the Technical Committee etc.) Results: charter, mailing list, Wiki, timeframe (e.g. for teleconferences, meetings, expected results etc.) 2012 Open Geospatial Consortium 46

47 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 2012 Open Geospatial Consortium 47

48 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 48

49 And what more? Everyone can always bring in a Change Request to and existing standards. OGC Members meet 4x a year during the OGC Technical Committee meetings. Save the Date! Next European OGC TC Meeting June 2012 in Exeter, UK hosted by the UK MetOffice Open Geospatial Consortium 49

58 Some last thoughts... Interoperability seems to be about the integration of information. What it s really about is the coordination of organizational behavior. David Schell Chairman and Founder OGC 2012 Open Geospatial Consortium 58

59 GovFuture - new Membership Level for Local and Subnational Government new membership option for local and state/provincial government agencies worldwide and for a very small fee (200US$/500US$) (new membership structure for different regions in the world coming soon) reflects OGC's increased emphasis on knowledge transfer learn about new developments in geospatial technology benefit from those developments understand and address legal and policy issues liaise with other levels of government More information at and Open Geospatial Consortium 59
