Excerpt from Appendix B of GFD-C.1: Where the OGF knows of rights, or claimed rights, the OGF secretariat shall attempt to obtain from the claimant of such rights, a written assurance that upon approval by the GFSG of the relevant OGF document(s), any party will be able to obtain the right to implement, use and distribute the technology or works when implementing, using or distributing technology based upon the specific specification(s) under openly specified, reasonable, non- discriminatory terms. The working group or research group proposing the use of the technology with respect to which the proprietary rights are claimed may assist the OGF secretariat in this effort. The results of this procedure shall not affect advancement of document, except that the GFSG may defer approval where a delay may facilitate the obtaining of such assurances. The results will, however, be recorded by the OGF Secretariat, and made available. The GFSG may also direct that a summary of the results be included in any GFD published containing the specification.

© 2006 Open Grid Forum 18 How XQuery is used XQuery is a suitable language for our needs XQuery used in separate domains Requirements matching Document management Different domain usage allows: Requirements matching Restricted XQuery XPath 2.0, really! Document management Unrestricted XQuery Any other XPath interpreter solution
