Well, that's what the "Community Profiles" are. So now you have TWO
long, dense, boring documents to read -- the standard and the profile!
The main game in town for Making OpenURL 1.0 Usable (maybe still the
only game, come to think of it) is the San Antonio Profile, or SAP for
short, which you can get here:
http://alcme.oclc.org/openurl/docs/pdf/SanAntonioProfile.pdf
Happily, it's only eight pages long (i.e. the same length as the
entire original OpenURL 0.1 specification). The bad news is, they are
incredible dense pages. Sample statement:
D.5.5 Transports
Transports define how to transport representations of
ContextObjects over the
network. Table D.7 lists the Transports supported by the San
Antonio Community
Profiles.
The By-Value OpenURL Transport and the By-Reference OpenURL
Transport (over HTTP and HTTPS) may be used to transport ContextObjects
represented by means of the Key/Encoded-Value and the XML ContextObject
Format. In case of the Key/Encoded-Value representation, only a single
ContextObject may be transported. In case of the XML
representation, one or more
ContextObjects may be transported.
The Inline OpenURL Transport may only be used to transport a single
ContextObject represented using the KEV ContextObject Format.
Have fun with that!
