1.22 Resolver

Records

The Goobi viewer offers resolvers to open worecordsks via an identifier (PI), an URN or a custom identifier.

Name

URL

Identifier

https://viewer.example.org/piresolver?id=PPN123456789

URN

https://viewer.example.org/resolver?urn=urn:nbn:de:hebis:66:fuldig-1946

Custom

https://viewer.example.org/resolver?field=ALLEGROID&identifier=ZDB001023124

The custom resolver can contain further fieldX and valueX combinations besides the mandatory parameters identifier and field, where X must be replaced by a consecutive number. This can be used for example to link to newspaper editions:

Example 1: https://viewer.example.org/resolver?field=PI_ANCHOR&identifier=000141932&field2=YEARMONTHDAY&value2=19630221

Example 2: https://viewer.example.org/resolver?field=PI_ANCHOR&identifier=000141932&field2=YEARMONTHDAY&value2=19630221&field3=DC&value3=periodical

The /piresolver?id= can also be addressed using the aliases /ppnresolver?id= and /epnresolver?id=.

The following options control the URL forwarding when opening the found record:

<urnresolver>
    <doRedirectInsteadofForward>false</doRedirectInsteadofForward>
</urnresolver>

Parameter

Description

doRedirectInsteadOfForward

If true, an HTTP redirect is executed instead of a forward when resolving. Default value is false.

The URN resolver can look for URNs in different Solr fields. For this purpose it is possible to specify a list of field names.

<urnresolver>
    <field>URN</field>
    <!-- <field>MD_INTERNAL_UNREGISTERED_URN</field> -->
</urnresolver>

Metadata

Furthermore, it is possible to open the source file of a record directly. Depending on whether the record comes from METS or LIDO, a different resolver is used. Either the PI (id=PI) or the URN (urn=URN) can be passed to these resolvers:

Name

URL

Generic PI

https://viewer.example.org/sourcefile?id=PPN123456789

METS PI

https://viewer.example.org/metsresolver?id=PPN123456789

METS URN

https://viewer.example.org/metsresolver?urn=urn:nbn:xx:000-12345678

LIDO PI

LIDO URN
