Chapter 7. URL format


Home Prev	Part IV. Using UnAPI	Next

Evergreen’s unAPI support includes access to many record types. For example, the following URL would fetch bib 267 in MODS32 along with holdings, volume, copy, and record attribute information:

https://example.org/opac/extras/unapi?id=tag::U2@bre/267{holdings_xml,acn,acp,mra}&format=mods32

To access the new unAPI features, the unAPI ID should have the following form:

tag::U2@
followed by class name, which may be
- bre (bibs)
- biblio_record_entry_feed (multiple bibs)
- acl (copy locations)
- acn (volumes)
- acnp (call number prefixes)
- acns (call number suffixes)
- acp (copies)
- acpn (copy notes)
- aou (org units)
- ascecm (copy stat cat entries)
- auri (located URIs)
- bmp (monographic parts)
- cbs (bib sources)
- ccs (copy statuses)
- circ (loan checkout and due dates)
- holdings_xml (holdings)
- mmr (metarecords)
- mmr_holdings_xml (metarecords with holdings)
- mmr_mra (metarecords with record attributes)
- mra (record attributes)
- sbsum (serial basic summaries)
- sdist (serial distributions)
- siss (serial issues)
- sisum (serial index summaries)
- sitem (serial items)
- sssum (serial supplement summaries)
- sstr (serial streams)
- ssub (serial subscriptions)
- sunit (serial units)
followed by /
followed by a record identifier (or in the case of the biblio_record_entry_feed class, multiple IDs separated by commas)
followed, optionally, by limit and offset in square brackets
followed, optionally, by a comma-separated list of "includes" enclosed in curly brackets. The list of includes is the same as the list of classes with the following addition:
- bre.extern (information from the non-MARC parts of a bib record)
followed, optionally, by / and org unit; "-" signifies the top of the org unit tree
followed, optionally, by / and org unit depth
followed, optionally, by / and a path. If the path is barcode and the class is acp, the record ID is taken to be a copy barcode rather than a copy ID; for example, in tag::U2@acp/ACQ140{acn,bre,mra}/-/0/barcode, ACQ140 is meant to be a copy barcode.
followed, optionally, by &format= and the format in which the record should be retrieved. If this part is omitted, the list of available formats will be retrieved.
