Proper encoding of identifier property in DataCatalog

[ivanmicetic]

How to encode the “identifier” property in DataCatalog specifications? Specs say PropertyValue|Text|URL and under description we find Bioschemas: identifier:accessURL,identifierPattern,exampleIdentifeir (MANY) giving several possibilities:

• URL or text example "identifier": "https://www.fairsharing.org/biodbcoreXXXXXX"
• bioschemas recommendation (my implementation, maybe incorrect): {"accessURL":"http://identifiers.org/mobidb/", “identifierPattern":"^[OPQ][0-9][A-Z0-9]{3}[0-9]|[A-NR-Z][0-9]([A-Z][A-Z0-9]{2}[0-9]){1,2}$”, "exampleIdentifier":"http://identifiers.org/mobidb:P10636"}
• schema.org PropertyValue: {"@type": "PropertyValue", "propertyID": "http://identifiers.org/", "value": "MIR:00000637"},"sameAs": "http://identifiers.org/mobidb"}

Main problem with URL/text example is that too few information are present, and it may be difficult to parse and use. In bioschemas example, it could be useful to add two new properties together with accessURL, the first specifying the identifying entity or organization (e.g. “identifierProvider”: ”identifiers.org”) and second, the name of collection/resource of the identifier (e.g. “identifierCollection”:[“mobidb”,”MIR:00000637”]).

The example in the profile gives a simple example of usage (copied below), is it sufficient?

{
"@type": "DataCatalog",
"identifier": "MIR:00000018"
}

Do we need the complexity proposed by @ivanmicetic for Bioschemas?
