Catalogue Services 3.0 SWG
Catalogue Services 3.0 SWG
1. Purpose of the Standards Working Group
The purpose of this Standards Working Group is to process change requests to the Catalogue Services Version 2.0.2 corrigendum and publish it as a Version 3.0 implementation standard. The SWG will achieve this objective by evaluating and processing change requests received from the Catalogue Working Group members in support the objectives, audience, and scope described herein.
2. Scope of Work
This SWG is focused on processing change requests on the Catalogue Services 2.0.2 implementation standard. The Scope of Work (SOW) will be to solicit, post, and process comments from the 30-day public comment period as well as all outstanding and planned Change Requests, evaluate each of the proposals, and edit the standard based on these Change Requests and related decisions of the SWG membership.
General areas of document enhancement will include the following items that will be entered through formal change requests:
Divide the document into four parts corresponding to the general model and each of three registered binding protocols: HTTP, Z39.50, and CORBA. This supports the ISO standard approach of base plus Parts.
Incorporate changes to the HTTP protocol binding Part that reflect current baseline practices within the catalogue community.
Specific change requests will be managed on the SWG wiki page with recommended resolution of comments and their resolution. Additional Change Requests may be addressed at the discretion of the SWG based on criticality of the change and available time and resources.
2.1 What is out of scope?
Only those change requests and comments submitted through the formal process as identified in the Policy and Procedures will be addressed. Therefore, any items suggested through emails, vocal discussions, etc will be outside of the scope of this SWG until formally submitted as a change request.
2.2 Specific Existing Work Used as Starting Point
The starting point for the work will be Version 2.0.2 of the "Catalogue Service Implementation Specification," (OGC 07-006r1).
2.3 How to Determine when Work of SWG has been Completed
The following criteria will be used to determine the completion of this SWG:
All Change Request Proposals submitted prior to April 30, 2008 have been reviewed and evaluated to the satisfaction of the SWG. This may include working the proposal, rejecting the proposal, or postponing the proposal to a later version.
A completed revision of the Catalogue Services version 3.0 standard documents have been produced and reviewed by the SWG and have been approved for submission to the TC for approval as an adopted standard.
3. Description of deliverables
The following deliverables will result from the work of this SWG:
A final version of the Catalogue Services Version 3.0 Standard document for submission to the TC.
Corresponding XML schemas associated with the Catalogue Services Version 3.0 Standard document.
The following schedule of activities is anticipated:
SWG activities are a continuation of a previously convened Revision Working Group. Prior members are automatically opted-in to the new SWG. New members will be invited to opt-in through announcement to the TC in March 2008.
Teleconferences will be held every third week on Mondays at 15:00UTC.
Candidate change requests will be posted to pending for consideration by the SWG before April 30, 2008.
Proposed document and schema changes to be presented to TC for information at the June 2008 TC meeting.
Resolve comments prior to posting in June 2008
Post document and schema for a 30-day comment period in early June 2008
Candidate standard with schema to be posted for vote three weeks prior to September 2008 TC meeting.
The above schedule is meant to serve as a guideline to the SWG in order to determine completion milestones. However, based on the actual Change Requests, completion dates may be adjusted to accommodate critical updates to the documents. Although all change requests will be addressed, some may be postponed due to the need to more quickly produce a document containing higher priority requests.
4. IPR Policy for this SWG
5. Anticipated Audience
The target audiences of the Catalogue Services version 3.0 include:
implementers of catalogue services solutions
developers and deployers of catalogue services profiles
users of catalogue services
6. Other informative information about the work of this SWG
a. Similar or applicable standards work
The proposed standard is based on abstract catalogue service design patterns from ISO IS-23950:1998 and its Web-based next generation "Search-WS" hosted by the OASIS organization. The HTTP protocol binding has a dependency on the Filter Encoding 1.1 specification and OGC Common Specification 1.1.0. Various profiles of catalogue services with other standards dependencies exist and will need to be harmonized with changes in this specification.
b. Details of first meeting
The first meeting of this SWG will be at the OGC Technical Committee meeting in St. Louis, March 2008.
c. Projected on-going meeting schedule
The work of this SWG will be carried out primarily by email and conference calls, with potential face-to-face meetings at OGC TC meetings as agreed to by the SWG members. The teleconference calls will be scheduled as-needed and posted to the OGC portal.
d. Supporters of this Charter
The following persons support this SWG and are committed to the Charter and projected meeting schedule.
