Hi Toby. WRT the draft spec for the REST spec "WS-Calendar Calendar Update and Synchronization with REST-based Services Version 1.0" I was a bit surprised to see the creation of property identifiers using the domain " docs.oasis-open.org/ " where the identifiers don't follow the expected pattern. Maybe this was was discussed in connection with other WS-Calendar TC spec approvals, but I don't recall it... I say "surprised" because we do indeed authorize the creation of identifiers for properties based upon URNs or HTTP-scheme URIs, but when the Internet domain " docs.oasis-open.org " is used, there's a restriction on construction of the identifier string for any "properties" (namespace), per details cited at [3] below. WD text was:   3.  Properties and link relations   3.1 Property and relation-type URIs   "Certain of these property URIs correspond to CalDAV    preconditions. Each URL is prefixed by the CalWS    relations and properties namespace:     http://docs.oasis-open.org/ns/wscal/calws (attested strings) http://docs.oasis-open.org/ns/wscal/calws http://docs.oasis-open.org/ns/wscal/calws/caldav/supported-calendar-data http://docs.oasis-open.org/ns/wscal/calws/calendar-collection http://docs.oasis-open.org/ns/wscal/calws/calws/timezone-service http://docs.oasis-open.org/ns/wscal/calws/child-collection http://docs.oasis-open.org/ns/wscal/calws/collection http://docs.oasis-open.org/ns/wscal/calws/created http://docs.oasis-open.org/ns/wscal/calws/current-principal-freebusy http://docs.oasis-open.org/ns/wscal/calws/description http://docs.oasis-open.org/ns/wscal/calws/displayname http://docs.oasis-open.org/ns/wscal/calws/last-modified http://docs.oasis-open.org/ns/wscal/calws/max-attendees-per-instance http://docs.oasis-open.org/ns/wscal/calws/max-date-time http://docs.oasis-open.org/ns/wscal/calws/max-instances http://docs.oasis-open.org/ns/wscal/calws/max-resource-size http://docs.oasis-open.org/ns/wscal/calws/min-date-time http://docs.oasis-open.org/ns/wscal/calws/owner http://docs.oasis-open.org/ns/wscal/calws/principal-freebusy http://docs.oasis-open.org/ns/wscal/calws/principal-home http://docs.oasis-open.org/ns/wscal/calws/supported-features http://docs.oasis-open.org/ns/wscal/calws/timezone http://docs.oasis-open.org/ns/wscal/calws/timezone-service http://docs.oasis-open.org/ns/wscal/calws:privilege-set Please let me know if there are any issues.  For properties, we would expect something like this in the initial identifier substring: a) http://docs.oasis-open.org/ns/ws-calendar/ b) http://docs.oasis-open.org/ws-calendar/ns/    [newer model] In both patterns, the TC name (tc-shortname) is required, because identifiers are allocated/managed on a TC-by-TC basis.  The TC "owns" that space of names/identifiers. Following the initial substring, per above, you could use anything else (reasonable) like: wscal/calws/caldav/ wscal/calws/calws/ wscal/calws/ wscal/[xxxx]/ calws/[xxxx]/ in the pattern to construct identifiers that terminate with (e.g.,) these substring elements/compnents - supported-calendar-data - calendar-collection - timezone-service - child-collection - collection - created - current-principal-freebusy - description - displayname - last-modified - max-attendees-per-instance - max-date-time etc - Robin [1] XML Namespace Identifiers and Namespace Documents http://docs.oasis-open.org/specGuidelines/ndr/namingDirectives.html#xml-namespaces [2] URI pattern: http://docs.oasis-open.org/[tc-shortname]/ns/xxxx http://docs.oasis-open.org/specGuidelines/ndr/namingDirectives.html#ns-URI-string-rules [3] Non-information resources     http://docs.oasis-open.org/specGuidelines/ndr/namingDirectives.html#nonInformationResources     "Non-information resources using identifiers associated with XML     namespaces may be based upon any HTTP scheme URI XML namespace     declared by the TC (i.e., identifiers for named properties,     functions, dialects, faults, actions, or any named message types).     Example: see the Link Relations URIs in one of the CMIS v1.0 XML     namespace documents (e.g.,     http://docs.oasis-open.org/ns/cmis/link/200908/allowableactions     http://docs.oasis-open.org/ns/cmis/link/200908/policies ). -- Robin Cover OASIS, Director of Information Services Editor, Cover Pages and XML Daily Newslink Email: robin@oasis-open.org Staff bio: http://www.oasis-open.org/people/staff/robin-cover Cover Pages: http://xml.coverpages.org/ Newsletter: http://xml.coverpages.org/newsletterArchive.html Tel: +1 972-296-1783
