NAME

koha-ark - Manage ARK identifiers in a Koha Catalog

VERSION

version 1.0.1

DESCRIPTION

Process biblio records from a Koha Catalog in order to update its ARK identifiers. See The ARK Identifier Scheme. The processing is driven by ARK_CONF Koha system preference. It's a json variable. For example:

{
  "ark": {
    "NMHA": "myspecial.institution.fr",
    "NAAN": "12345",
    "ARK": "http://{NMHA}/ark:/{NAAN}/catalog{id}",
    "koha": {
      "id": { "tag": "099", "letter": "a" },
      "ark": { "tag": "003" }
    }
  }
}

ARK_CONF system preference must contains several elements:

• NMHA — Name Mapping Authority Hostport. Usually it's a hostname, the hostname of the Koha system itself, or the hostname of a proxy server (or link resolver).

• NAAN — Name Assigning Authority Number. It's a number identifying the institution, ie the Library using Koha. This number is provided for example by the California Digital Library (CDL),

• ARK — It's a template used to build the ARK. Three placeholders can be used in the template: NMHA and NAAN from ARK_CONF, and id (Koha biblio record unique identifier extracted from koha.id field).

• koha.id — The biblio record field which contains Koha unique id (biblionumber or another id). Contains 2 variables: tag and letter, si it could be a control or a standard field. For example, {"tag": "001"} or {"tag": "099", "letter": "a"}.

• koha.ark — The biblio record field used to store the ARK. It could be a control or standard field. That's this field in which this script will store the generated field. This is also the field that this script can clear entirely.

There are two commands: clear and update

clear

koha-ark clear clears the ARK field (koha.ark variable) in all biblio records of the Catalog.

update

koha-ark update processes all biblio that have an empty ARK field. The ARK field is created with the appropriate ARK identifier. The ARK is build based on ARK variable from ARK_CONF. For the above ARK_CONF, the biblio record that has 9877 biblionumber will have this in 003 field:

http://myspecial.institution.fr/ark:/12345/biblio9877
