Bodleian MMM

June 2018

Main contribution by Andrew Morrison.

Background

The TEI XML format has been chosen for detailed cataloguing of manuscripts at the Bodleian (and elsewhere) because of its rich and flexible syntax. A custom schema, including mainly the TEI P5 modules for manuscript descriptions, has been created, with minor variations for Western, Islamic and Oriental manuscripts.

The Medieval manuscripts colletions are catalogued in the most detail, with a lot of work having been done to create local authority files for works, people and places - also in TEI - by Matthew Holford. These files are stored in a GitHub repository, with a web site built using open source technologies including XSLT, XQuery, Solr and Blacklight providing a user interface.

Aims

To express the key metadata fields and relationships between entities (manuscripts, parts, works, authors and other people, places) as Linked Data by simplifying the TEI data structure, and mapping that to CIDOC-CRM and FRBRoo ontologies using the 3M tool.

A particular focus was on mapping provenance information to enable the Mapping Manuscript Migrations project to track the ownership history of manuscripts. Some examples of the use of SPARQL to query origin, provenance, and acquisition events by location and time are included in a presentation given in June 2018.

Simplification of TEI manuscript descriptions

The source TEI data can be complex and hierarchical, with potentially a manuscript divided into several parts, each with its own history and containing works-within-works (e.g. a collection of poetry and individual poems.)

Provenance information has been catalogued in a variety of different styles (e.g. a single XML element describing the entire history of the manuscript or multitple elements each recounting one event). Dates might be encoded with date tags or attributes on the provenance element. So an XQuery script was developed to extract the relevant information in a more rigid structure, for easier mapping in the 3M tool.

The schema of the resulting simplified XML format evolved in response to changing requirements, so isn't as logically-structured as it could be, but the XSD can be viewed here. TODO: Add link to XSD file

Reconciliation

The names of people (including authors and former owners), works, organizations, and places in manuscript descriptions are controlled by local authority files.

These have been, in turn, manually reconcilated with URIs of records in external authorities such as VIAF, Library of Congress, Bibliothèque nationale de France, Système Universitaire de Documentation, Gemeinsame Normdatei, and WikiData.

Instances in the manuscripts are linked to entries in the local authority files via key attributes. For example, each of the five copies in five different manuscripts of De quantitate animae by Augustinus have a key of work_778, corresponding to the entry with that ID in local works authority file. Augustinus himself has a local persons authority file entry with an ID of 'person_66806872', to which all mentions of him in the manuscript refer, and which has been reconciled with all the aforementioned global authories.

The script to generate simplified XML turns those into URIs. The authority files themselves, being essentially flat lists, were mapped in the 3M tool directly.

Contacts

Step by step procedure for export

  1. Clone [email protected]:bodleian/medieval-mss.git to your computer
  2. cd processing/analysis/
  3. Run ./simplified-xml-for-3m.sh
  4. cd results/
  5. Check simplified-xml-for-3m.log in case of broken input files, unreadable dates, or unrecognized languages
  6. The output is written to simplified-xml-for-3m.xml

Detailed review of data in individual fields

Field list and mapping

The following table represents the mapping of TEI elements/attributes to the simplified XML and from there to the ontologies configured in the 3M tool. It is presented roughly in order of hierarchy in the TEI:

provenance

crm:E5_Event

This assumes each provenance in the TEI is a single event, which may not always be the case.

provenance/@xml:id

URIorUUID

ID generated by the script to be unique for each provenance event, e.g. manuscript_6327_prov3

provenance/text

crm:P3_has_note > Literal

The entire text describing a stage in the provenance of the manuscript

provenance/date

crm:P4_has_time-span > crm:E52_Time-Span

Each of these child elements of provenance themselves have the same child elements listed above when they’re not in provenance. The mapping here relates them to the specific stage in the provenance of the manuscript.

inscription

crm:E34_Inscription

Inscriptions are simply provenances whose text start with a single-quote mark, e.g. 'Dominus Johannes Blathe', incised on the binding. All the same information is extracted from the TEI, but it is mapped differently to the ontology.

TODO

  • The transformation at its current state assumes that the records are facts. It would be useful to consider a mapping using the CRMinf to model propositions and deductions instead.
