REPORT September 16, 2003 OGC Update 6 Other Motions Accept the updated Technical Document Baseline also known as Document 1 (OGC Document r1) as the normative reference for our technical document baseline. (Passed) –The Technical Baseline is a list of all the "active" OGC documents and their status. The TC recommends to the PC that the document XML Binary Encoding ( r8) (also known as BXML) be shared with the W3C for consideration (Passed) –There was a feeling among some of the members that BXML would be of interest to the greater XML community. Hence the idea that we would advise the W3C of its publication. The TC recommends to the PC that an e-vote or approval of version 1.0 of the Web Coverage Service Specification be allowed. (Passed) –The WCS Revision Working Group has reached consensus on what should be in 1.0 of the spec and expects to be finished with the document before the next meeting in October. This motion lets them ask for an electronic vote in the summer. The TC recommends to the PC that an e-vote for approval of version 1.1 of the Web Feature Service Specification be allowed. –The WFS Revision Working Group has reached consensus on what should be in 1.1 of the spec and expects to be finished with the document before the nex meeting in October. This motion lets them ask for an electronic vote in the summer.

REPORT September 16, 2003 OGC Update 7 WCS The OGC Technical Committee is currently voting on the Web Coverage Service (WCS), v1.0, as an OGC Implementation Specification. Meanwhile, members of the WCS Revision Working Group have begun implementing WCS 1.0 in clients and servers Upcoming OWS-2 testbed will further exercise and develop the specification. Bernhard will say a little more about WCS…

REPORT September 16, 2003 OGC Update 8 WFS & Filter Editors revision to be completed in mid- September RWG will review & revise some more E-Vote by RWG, then e-vote by TC Probable outcome: end of 2003 or early 2004 for final adopted version 1.1

REPORT September 16, 2003 OGC Update 9 WMS WMS in tight synchronization with ISO version Revised version sent to ISO on as DIS. – –Comments on DIS must be submitted via ISO channels Same version to be submitted to OGC for vote as WMS Situation is interesting because –ISO now has a newer version than OGC (but its still DIS) –There is a chance (small) that OGCs could differ from ISO DIS

REPORT September 16, 2003 OGC Update 10 Web Map Context Stable at 1.0 Early interest in quick update to 2.0 seems to have died. 10+ Companies in have implemented it Endorsed by GeoConnections for web mapping application state –Being integrated into related projects At least two open source implementations –UMN MapServer –CWC2/Chameleon

REPORT September 16, 2003 OGC Update 11 Catalog RWG is working on version 2.0 –Doug Nebert - Chair –Stateless Catalog interface –General model Query Language Group –Lou Reich - Chair –Expansion of OGC Common Query Language, Filter Encoding, and combination with XML Query Vendor Group –Working on an RFC based on OWS 1.2 SIM/RIM –RFC would be considered a profile of Catalog 2.0 Prognosis - This is not quick work… –I.e. dont expect anything in 2003 or early 2004

REPORT September 16, 2003 OGC Update 12 Geospatial One Stop Geospatial One Stop Portal Initiative Look at Whats New section… –Provide portal based on OGC services to provide access to (eventually all) US Government spatial data holdings –Initial demonstration in June, 2003 –ESRI was also hired to build an independent portal –The two portals were compared in June and the ESRI portal was chosen as the winner. –OGC is to consult to ensure the portal will follow standards. –The best review of news material about this can be found here:

REPORT September 16, 2003 OGC Update 13 Open GIS Consortium (Europe) Limited Formed in 2001 Organised and operated as a non-stock, not for profit company limited by guarantee, organised under The Companies Act 1985 of England and Wales. OGCE is a wholly-owned subsidiary of the Open GIS Consortium, Inc. (OGC). OGCEs purpose is to conduct business in Europe on behalf of OGCs mission, goals, and objectives and specifically to: –Promote the development and use of advanced open systems standards and techniques to enable the full integration of geospatial data and geoprocessing resources into mainstream computing and widespread use of interoperable, commercial geoprocessing software throughout the global information infrastructure; and –Represent the European-based membership of OGC in membership organisations/associations in Europe with similar vision and mission to that of the Company, including agencies, collaborators and affiliates of the European Commission.

REPORT September 16, 2003 OGC Update 14 OGCEs Sandbox Respond to the European market –Participate in European Community actions where interoperability is required INSPIRE GMES Regional and local SDI Domain initiatives, projects and programmes Engage the European Community to fully participate in the OGC vision –Drive take up & adoption of interoperable geoprocessing with projects based on user driven requirements, OpenGIS specifications, SCOTS software and engineering development processes Promote the OGC vision in Europe –Facilitate testbeds and pilots and other OGC structures for engagement –Assist organisations in Europe in programs where interoperability is a focus

REPORT September 16, 2003 OGC Update 15 Summary OGC is still alive and kicking –GOS Portal was a bit of a setback –Still seems to be working on too many fronts –Unclear how OpenLS really fits in +Increasing number of implementations +Still plenty of interest and participation +WCS will hit version 1 and should prove useful to the EO community

REPORT September 16, 2003 OGC Update 16 Further reading These slides provide some additional information about some of the items in the previous slides.

REPORT September 16, 2003 OGC Update 17 Binary-XML Encoding Specification (03-002r8) Describes an encoding of XML in a binary format that both reduces the volume of data that has to be transferred between applications and allows for very efficient client-side ingestion of the data. BXML provides a lossless encoding of XML data so the receiving end can reconstitute the entire structure.

REPORT September 16, 2003 OGC Update 18 Critical Infrastructure Collaborative Environment Architecture [The] Critical Infrastructure Collaborative Environment (CICE) [...] open, distributed processing environment crosses organizational boundaries and includes a variety of components deployed within multiple communities. The CICE leverages OGC Web Services to enable: The publication of the availabilityof critical infrastructure services and data; The registration and categorization of published service and data providers; and The discovery of needed critical infrastructure services and data The integration and application of critical infrastructure services and data Critical infrastructure is a very broad term that encompasses many large-scale systems in a range of sectors: energy, telecommunications, transportation, public health services, and more. Safeguarding such systems involves a myriad of political, economic, and legal issues that will not be raised here. Rather, the CICE is more about the creation and maintenance of a common information operating environment to support operational, planning, and decision-making activities associated with critical infrastructure protection.

REPORT September 16, 2003 OGC Update 19 GO-1 Application Objects Report (03-064r1) This document is a draft of the OpenGIS Application Objects Implementation Specification, hereinafter AOS. The AOS is one of a family of specifications that make up the OGC Geographic Objects activity. The Geographic Objects Initiative was established to develop an open set of common, lightweight, language-independent abstractions for describing, managing, rendering, and manipulating geometric and geographic objects within an application programming environment. This document defines that set of vendor-neutral, Object-Oriented geometric and geographic object abstractions. It provides both an abstract object specification (in UML) and a JAVA specific profile to that that specification. The language-specific binding specifications themselves serve as open Application Programmer Interface (API) specifications for these Application Objects.

It also outlines the scope and relationship of OpenLS with respect to other specifications and standardization activities. The primary objective of OpenLS s to define access to the Core Services and Abstract Data Types (ADT) that comprise the GeoMobility Server, an open location services platform. –03-007r1: This OpenGIS Implementation Specification defines the interfaces for OpenGIS ® Location Services (OpenLS): Part 6 - Navigation Service (formerly the Full Profile of the Route Determination Service), which is part of the GeoMobility Server (GMS), an open location services platform.
