New ISO work item proposal: SDShare

Wednesday, January 20th, 2010

The ISO committee (SC34) has sent out a proposal for a new ISO work item, called SDShare. SC34 is now doing a 3-month ballot to see if member countries wish to develop this into a full ISO standard.

The proposal defines SDShare as follows:

The proposal specifies an underlying syndication protocol for the exchange of information about semantic descriptions. The protocol conforms to the Atom Syndication Format and the Topic Maps Data Model (TMDM) and works with semantic descriptions represented as in XTM 1.0, XTM 2.0 and RDF/XML. It defines layers of syndication feeds that a conforming application must provide. Finally it defines algorithms for the provisions and processing of the different feeds on servers and clients.

For those who don’t recognize it, this is the SDShare protocol already developed by NetworkedPlanet and others, for transmitting streams of changes to a topic map using an Atom feed.

XTM 2.1 ballot started

Friday, December 4th, 2009

ISO SC34 has now officially started the process to revise XTM 2.0 (ISO 13250-3:2007). The purpose of this is to revise it to XTM 2.1 as informally agreed by WG3 at the Leipzig meeting. Note the time table at the end of the revision proposal. If the Stockholm meeting approves the proposal we should have an official ISO-approved XTM 2.1 by April 2011.

Notes from Leipzig ISO meeting

Thursday, November 26th, 2009

The notes from the first day of the Leipzig ISO meeting have now been posted. Here’s a quick summary of the status of each of the items discussed.

XTM 2.1

The first set of notes deals with XTM 2.1, and basically the XTM 2.1 proposal was passed by the committee. A few very minor additions were made, such as the decision to apply for a registered MIME-type for XTM, but the substance of the proposal is as it was when Lars Heuer first made it.

The process of applying for an XTM MIME-type has started, with a brief discussion on the ietf-types mailing list, and the application has been submitted as an Internet-Draft. So far there has been no reply to the application (which is normal).

The first implementation of XTM 2.1 is already released, in Mappa’s tm.reader.xtm version 0.1.5.

However, it will take a while before XTM 2.1 becomes an official ISO standard. The editors are currently requesting that SC34 start the revision process of ISO 13250-3 (which is XTM). This will probably be approved at the Stockholm meeting in March, and the XTM 2.1 draft will then go out for a 3-month CD ballot. After that it will go through the FCD, FDIS, and IS stages as quickly as possible.

TMQL

The second set of notes is about the new proposed TMQL path language. The main thing to take away here is that the proposal met a generally positive reception, but that many open questions remain.

The next step is for the editors to do some editing, and come back with a more complete proposal based on the feedback they received.

TMCL

The third set of notes is about TMCL and the decisions made on it. The decisions made were mostly of the “we won’t do this”-type or minor extensions. A new draft should follow before too long. (The Seattle notes were delayed, but are now also available.)

A TMQL path language proposal

Thursday, November 5th, 2009

The TMQL editors have published a set of slides describing their proposal for the path language part of TMQL. This is the first official glimpse of where TMQL might be headed under its new editors. The slides describe now just the path language, but also a number of issues with the proposal, and alternative designs which might be chosen.

The editors are actively seeking feedback before the meeting, and there is still time to comment. Feedback might be anything from “I like this language!” or “I prefer the previous path language!” through comments on the issues or design alternatives, to new proposals and issues.

TMCL issues

Thursday, November 5th, 2009

A set of slides describing the open TMCL issues to be discussed at the ISO meeting in Leipzig next week have been published. The editors are actively seeking feedback on these issues, and there is still time to comment before the meeting.

A proposal for XTM 2.1

Friday, October 30th, 2009

Lars Heuer posted a proposal for XTM 2.1 on the SC34WG3 mailing list. Essentially, his proposal is to relax some of the restrictions in XTM 2.0 and to make it possible to refer directly to topics with subject identifiers and subject locators. The proposal has had a quite positive reception, and will be discussed at the ISO meeting in Leipzig in mid-November.

The editors of XTM have published a set of slides for the discussion at the ISO meeting. They are looking for community feedback on the proposal in advance of the meeting.

Norwegian ISO committee seeking participation

Wednesday, October 21st, 2009

The Norwegian ISO committee mirroring the international SC34, officially known as SNK/185, is planning to start holding regular meetings to discuss Norwegian positions on the ISO standards that SC34 develops (primarily Topic Maps, OOXML, ODF, and DSDL). This would enable Norwegian members to stay informed about ongoing work and to provide input to it (and even vote on it) without having to travel to international meetings. They would, however, be required to join Standard Norge.

If anyone is interested, please contact either Bjørnhild Sæterøy at Standard Norge, or Lars Marius Garshol.

New TMCL draft published

Monday, October 19th, 2009

The editors have published a new TMCL draft, which will most likely go out for FDIS (Final Draft International Standard) ballot after the Leipzig meeting in November. This means that the editors consider TMCL to be just about finished.

In the official announcement the editors call for review and implementation of the current draft.

ISO: Topic Maps intro and TMRM

ISO (SC34, really) has just posted three new documents on Topic Maps:

New draft of ISO 13250-1

Thursday, July 30th, 2009

ISO 13250-1 is a technical report that’s meant to serve as an introduction to the whole family of Topic Maps standards. Editors Patrick Durusau and Motomu Naito have now published a rough editor’s draft, and are asking for feedback from the community. More detail can be found in the announcement.
