Regarding BPINS:

I am planning to put forth a replacement for the BPINS scheme. While the current BPINS scheme conforms to the URI syntax, the planned replacement scheme will have URNs. I am fairly sure that the challenge with the BPINS' URIs is that an RFC will be needed to define the bpid, btid, and bcid "protocols." If we are going to define a new internet protocol, something like "ebumlreg" would be better :^)

I am planning to meet with Kathryn of the Reg/Rep group this week.

Subject: [ebxml-cppa] Data type for uuid attribute in ProcessSpecification element in ebBPSS1.02.xsd

The following naming scheme is recommended in http://www.ebxml.org/specs/bpWS.doc:

A BPINS naming scheme format is defined by :

bpid:<agency>:<agency-id>:<business-process-name>$<major-version-number>.<minor-version-number>

In ebBPSS1.02.xsd, the uuid attribute in the ProcessSpecification element is defined to be of type xsd:ID. This is in conflict with the above recommendation for assigning uuid's for ProcessSpecification because the character ':' is not allowed in the type "xsd:ID".

I think uuid should be redefined to be of type "anyURI". If it is necessary to ensure that the ProcessSpecification elements within a BPSS instance have unique uuid's, then perhaps an explicit uniqueness constraint can be defined.

Excerpts from http://www.w3.org/TR/xmlschema-2/#ID:

3.3.8 ID

[Definition:] ID represents the ID attribute type from [XML 1.0 (Second Edition)]. The ·value space· of ID is the set of all strings that ·match· the NCName production in [Namespaces in XML]. The ·lexical space· of ID is the set of all strings that ·match· the NCName production in [Namespaces in XML]. The ·base type· of ID is NCName.

[4] NCName ::= (Letter | '_') (NCNameChar)* /* An XML Name, minus the ":" */

[5] NCNameChar ::= Letter | Digit | '.' | '-' | '_' | CombiningChar | Extender
