RE: Question about identifiers

Hi,

I like the guidance under the URI-Strategy under Hierarchical URIs generally, but have some reservations to this intelligent identifiers approach.
For metadata access I think it is a good thing.  Most metadata for an individual features will usually reside at the dataset or collection (better term) level.  This hierarchical approach makes this metadata easy to access.

But this built in intelligence makes the permanence of the URIs more difficult.  For example, administrative boundaries change through mergers and annexations.  A spatial thing that was in one collection is now in another.  The URIs for these things then confuse more than help.  URI redirects are one way to deal with this, but perhaps tracking these relationships through applied ontologies such as skos:broader and skos:narrower is the better practice?

No answers from me here, just questions.

Cheers,
Byron

Hi Josh,

Coming back to the telecon yesterday:


<joshlieberman> Should identifiers be part of a system for the features of interest?

joshlieberman: making identifiers part of a system, where the features are part of the system?
... for example corresponding to paths in a taxonomy

Linda: no answer right now, will have to think about it

Were you talking about recommending some system for creating HTTP URI identifiers, i.e. some sort of URI strategy or pattern? Specifically where the features can be organised into some system like a hierarchy, as with administrative regions? There are some examples from Geonovums testbed here
https://github.com/geo4web-testbed/topic3/wiki/URI-Strategy under Hierarchical URIs.

Just trying to understand what you mean… we could add some guidance to the BP about this. I think that would be helpful.

Linda
