Hey all, As some of you are aware the Open Geospatial Consortium (OGC) has adopted a policy to alter the XLink dependency in many of the XML schemas maintained by the OGC and used for several Web Services and for some GML.
This situation arises because the OGC adopted their own 'stub' XLink schema back before the W3C had published any official schema for XLink. Now that there is an offical W3C schema, the OGC is attempting to re-align all existing OGC schemas on those new XLink schemas. The FAQ (see below), explains that they chose to consider these backwards incompatible changes to be 'fixes' allowing for this approach retroactively 'fixing' all the schemas to reference the official W3C XML Schema. Since the 'fix' is backwards incompatible, that approach surprised many of us. When the issue last came up, I took action to press for more explanation from the OGC folk, since I am involved over there. Carl Reed, the Chair of the Technical Committee at the OGC (where all the standards work happens), has just released several documents related to the transition. Back in April, Carl published a blog entry discussing the process: http://www.opengeospatial.org/blog/1597 He has now published two documents, a letter and a FAQ: On Thu, 2012-06-28 at 16:33 -0400, [email protected] wrote: > Dear OGC Members > > Based on final input from the TC and the PC concerning the transition > of the OGC XLink schema to the W3C XLink 1.1 schema, I developed an > overview letter with updated information.

Finally, the OGC has set up an email list for discussions related to the transition. https://lists.opengeospatial.org/mailman/listinfo/beta-schemas Carl has assured me they will open the archives for public viewing so we don't all have to sign up to see the tone and content of the discussion. These documents are not totally satisfactory but are probably all we are going to get on the subject. For instance, I do not understand the impact on their certification process: all their certified services will stop being compatible after the transition. So for those who are interested, there is ow a little more information and a mailing list for contact and discussion. cheers, ~adrian _______________________________________________ Discuss mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/discuss
