6. REPORT September 16, 2003 OGC Update 6 Other Motions Accept the updated Technical Document Baseline also known as Document 1 (OGC Document 03-053r1) 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 (03- 002r8) (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.

7. 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…

8. 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

9. REPORT September 16, 2003 OGC Update 9 WMS WMS in tight synchronization with ISO version Revised version sent to ISO on 2003-08-31 as DIS. –http://www.digitalearth.gov/wmt/docs/iso19128-DIS.doc –Comments on DIS must be submitted via ISO channels Same version to be submitted to OGC for vote as WMS 1.2.0 Situation is interesting because –ISO now has a newer version than OGC (but its still DIS) –There is a chance (small) that OGCs 1.2.0 could differ from ISO DIS

10. 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

15. 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

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

17. 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.

18. 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.

19. 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.

20. REPORT September 16, 2003 OGC Update 20 Open Location Services OpenGIS Location Services (OpenLS) Implementation Specification RFC was approved –03-006r1: This OpenGIS® Implementation Specification describes OpenGIS® Location Services (OpenLS): Core Services, Parts 1-5, also known as the GeoMobility Server (GMS), an open platform for location-based application services. 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.
