Explanation of register structure

Each item in this register is identified as urn:cgi:registerItem:CGI:register:{authority}_{registerName}[_{version}]

The value in the registerName field of an item defines the token that shall be used as the value of the {registerName} element in a URN constructed according to the CGIIdentifierScheme.

The value in the version field of an item defines the token that shall be used as the value of the (optional) {version} element in a URN constructed according to the CGIIdentifierScheme.

The Public Resource Identifier for each register is urn:cgi:register:{authority}:{registerName}[:{version}] per the definition of the ResourceSpecificString in urn:cgi:registerItem:resourceClass:register.

The locator for each register is given in the Resource Locator field.

The value in the authority field of an item shall be a value from the authority field of an item in the CGIAuthorityRegister.

How many registers per resource class?

The "Resource specific string structure" currently allows for more than one register per resource class, through the (optional) "registerName" field, which is in addition to the CGIResource field.

However, it is not clear if this is required for all, or even any classes. Multiple feature-type registers may define distinct feature-type catalogues under CGI governance. But the schema affiliation of a feature-type is already accounted for by the "schema" field within the feature-type name.

What is the relationship between "schema" and "feature-type catalogue"? ...

should we add a register for OWL ontologies? Steve Richard

-- SteveRichard - 2010-01-04

What kind of resource is an OWL ontology? Is there an existing entry in CGIResourceClassRegister that is suitable?

-- SimonCox - 2010-01-05

I see that the ClassifierScheme register header notes say its for lexicons, vocabularies, and ontologies, so looks like they could fit in there. There isn't a clear cut reason to proliferate the number of registers.

-- SteveRichard - 2010-01-06

Yep - that was my thinking too.
