All geographical locations should have a PLACE-type record (prefixed LOC and stored in the Places repository), with co-ordinates and administrative division provided wherever possible.

At the same time, all repositories (libraries/archives/collections where manuscripts are preserved, including private collections, churches, monasteries, etc.) should have an INSTITUTION-type record (prefixed INS and stored in the Institutions repository).

A repository is a different conceptual entity from place: potentially a repository/library may move in space; and at the same time multiple repositories may share the same coordinates.

If you need to mark up a locality (mentioned in a work, or relevant for a manuscript, a person or a place) refer to a record of PLACE-type (creating one if necessary).

If you need to refer to a manuscript repository, in particular to link <repository>↗ within the <msIdentifier>↗ of a manuscript description, please refer to a record of INSTITUTION-type (creating one if necessary).

If you need to refer to a manuscript repository which is a church or a monastery already present among the Places (either because it has been inherited from the initial list of authority files, or created in another context) but not among the Institutions please proceed as follows :

1. create a new repository record and assign an ID (prefixed INS).

2. leave the place record there, check the already existing references to this place. This can be done either with xpath in Oxygen or on the website looking at related entities.

3. modify those references that point to a repository and not to a place, if any.

4. link the place and repository by adding a relation of the skos:exactMatch type as e.g. in ʿUra Qirqos

   
                   <listRelation>
                       <relation name="skos:exactMatch" active="INS0017UM" passive="LOC6063UraMas"></relation>
                   </listRelation>
