Version 1.2 Draft, 2013-09-09
This document describes the NorZIG profile for SRU (Search/Retrieval via URL) 1. The profile is based on the NorZIG Z39.50 Profile Version 2.1.
The purpose of the document is to promote interoperability between Norwegian SRU services. The intended audience is implementers of such services in Norway.
NorZIG is an acronym for the Norwegian Z39.50 Interest Group.
NorZIG-compliant servers must support the SRU base profile and CQL level 1 in addition to the requirements described in this document.
NorZIG-compliant servers must choose cql.anyIndexes as the default index when responding to term-only CQL queries.
If an index used in a CQL query is not supported in the native database, the server must fail the search and return diagnostic number 16 (Unsupported index) from the SRU List of Diagnostics.
NorZIG-compliant servers must support the full NorZIG context set.
The recommednded prefix for the NorZIG context set is norzig and its unique identifier is info:srw/profile/15/norzig-1.1.
In addition to the NorZIG context set, NorZIG-compliant SRU servers must support CQL queries using several indexes from other context sets. These context sets are:
| Context set | Version | Short name | Identifier |
|---|---|---|---|
| Bibliographic searching | 1.0 | bib | info:srw/cql-context-set/1/bib-v1 |
| CQL | 1.2 | cql | info:srw/cql-context-set/1/cql-v1.2 |
| Dublin Core | 1.1 | dc | info:srw/cql-context-set/1/dc-v1.1 |
| Record metadata | 1.1 | rec | info:srw/cql-context-set/2/rec-1.1 |
The following indexes and modifiers must be supported:
| Index name | Access point 2 | Description | Modifier | Values |
|---|---|---|---|---|
| cql.anyIndexes | Any | |||
| bib.audience | Intellectual level | A value defined in NORMARC tag 008, position 22 should be used | ||
| bib.classification | Dewey, UDC, Local class number | bib.classAuthority | dewey, udc, local | |
| dc.creator | Author, Function | bib.role | A value from BSMARC, attachment 4 (which means that bib.roleAuthority is bsmarc by default) | |
| dc.date | Date of publication (year) | |||
| bib.genre | Literary form | The values in use are 0 (non-fiction) and 1 (fiction) | ||
| dc.identifier | ISBN, ISSN, National bibliography number, Doc-id | bib.identifierAuthority | isbn, issn, nb, local | |
| rec.identifier | Local Number | |||
| dc.language | Language code | |||
| bib.nameConference | Conference name, Author name (conference) | bib.role | creator | |
| bib.nameCorporate | Corporate name, Author name (corporate) | bib.role | creator | |
| dc.subject | Subject | bib.subjectAuthority | humord (a term from Humord, which is a thesaurus for the humanities and adjacent disciplines in the Norwegian language), tekord (a term from Tekord, which is the collection of subject headings used at the Norwegian University of Science and Technology (NTNU)) | |
| dc.title | Title | |||
| bib.titleSeries | Title series |
The response documents from NorZIG-compliant SRU servers must be UTF-8 encoded.
NorZIG-compliant SRU servers must support the Dublin Core record schema, and at least one of the MARC record schemas listed below:
| Short name | Identifier | Description |
|---|---|---|
| dc | info:srw/schema/1/dc-v1.1 | The Dublin Core schema |
| marc21 | info:lc/xmlns/marcxchange-v1 | The MarcXchange schema 3 |
| normarc | info:lc/xmlns/marcxchange-v1 | The MarcXchange schema 4 |
| normarc_embedded | info:lc/xmlns/marcxchange-v1 | The MarcXchange schema 5 |
| marc21_embedded | info:lc/xmlns/marcxchange-v1 | The MarcXchange schema 6 |
| marc21_holdings | info:lc/xmlns/marcxchange-v1 | The MarcXchange schema 7 |
