Annex A: GEO Attribute Set
Contents
The GEO Profile requires clients and servers to support the GEO Attribute Set {ANSI-standard-Z39.50 3 9}, as specified in this Annex. For interoperability with Bib-1 and GILS clients, GEO servers must also recognize the Bib-1 {ANSI-standard-Z39.50 3 1} and GILS {ANSI-standard-Z39.50 3 5} Attribute Sets.
A.1. Attribute Types
The GEO Profile requires clients and servers to support the following Bib-1 Attribute Types:
- Use (1)
- Relation (2)
- Structure (4)
Optionally, a server may also support the Truncation (5) Attribute Type.
A.2. Use Attributes
The GEO Attribute Set inherits some Use Attributes from the Bib-1 and GILS Attribute Sets. Use Attributes whose values are between 1 and 1999 are from the Bib-1 Attribute Set, and Use Attributes between 2000 and 2999 are from the GILS Attribute Set. Additional GEO Use Attributes that cannot be mapped to Bib-1 or GILS are numbered from 3000 through 3999. With the exception of the Any and Anywhere Use Attributes, all Use Attributes map to an element in the GEO Schema (see Annex C). Not all Use Attributes are expected to be available for search. See Annex B for a list of the mandatory Use Attributes.
For convenience, the Use Attributes are tabulated as follows:
The tables below provide the name and value of each Use Attribute and its corresponding SGML element tag from the GEO Schema.
