Each object in contemporary cultural heritage collections has its own history and its own historical significance, as Neil McGregor vividly demonstrated with one hundred objects chosen from the collections of the British Museum (McGregor 2010). An important part of that history is the process by which each object came to reside in its current location and its current collection. Each object has usually been part of a series of collections over its lifetime, and this movement of objects between collections has its own history. Similarly, each collection has its own history of formation and (usually) dispersal. These collections include personal and individual collections, private institutional collections and modern public collections.

These relationships between cultural objects, collectors and collections over time are an important example of what Alan Liu has described as “network archaeology” (Liu 2012) – the recovery and analysis of cultural, social and artistic relationships at a particular period of time. As well as studying how and why some objects survived while others did not, and how and why the ownership of these objects changed, this “network archaeology” can also address several larger research questions. Cultural collections can reflect broader historical trends and are shaped by them. In the European context, these include the dissolution of religious institutions, the decline of royal and aristocratic patronage, the rise of public cultural institutions (especially museums and libraries), the emergence of wealthy collectors in the industrial era, European global expansion and imperial power, and the repatriation of cultural objects. The network of relationships between people and institutions involved in the ownership and transmission of cultural collections can also reveal a good deal about the more general networks of cultural influence and social and political relationships in a particular society.

In the nineteenth century, the English collector Sir Thomas Phillipps (1792-1872) assembled the largest private collection of European medieval and early modern manuscripts and documents. It is estimated to have contained more than 40,000 items, making it considerably larger than most of the collections in public institutions today, and included many manuscripts of considerable historical, textual and artistic significance. The manuscripts had very varied geographical origins across Western Europe, are written in various different European languages, and cover a wide range of different subjects and topics. Their modern locations are spread across the globe – the dispersal of the Phillipps Collection took place gradually over more than one hundred years, and numerous institutions and collectors were involved. As a result, the history of the Phillipps Collection provides a much richer and more varied set of data than a single contemporary institutional collection would provide.

In this paper, I will report on a project to reconstruct and analyse the history and provenance of the manuscripts which formed the Phillipps Collection. The scale of the Phillipps Collection has proved a significant challenge to traditional research methods in the past. The English librarian A.N.L. Munby spent more than a decade compiling a overview of Phillipps’ collecting activities and of the dispersal of the collection up to the mid-1950s (Munby 1951-1960). Several major institutions (including the British Library, the Bodleian Library, and Cambridge University Library) maintained for several decades a series of manual lists and indexes for transactions involving Phillipps manuscripts.

In this project I am employing innovative data modeling and analysis techniques to build a digital environment for tracing the entire history of these manuscripts, as far as it can be known. I am interested in mapping the provenance events and ownership networks which, taken together, constitute the history of these thousands of manuscripts over hundreds of years.

My paper will focus particularly on four key technical aspects of the project.

  1. Frameworks for modeling and representing the data relating to ownership and provenance, using an event-based approach.
    Events are central to provenance research, but they have proved difficult to represent in existing ontologies and data models, with a variety of different approaches being used. I will discuss the various alternatives – including CIDOC-CRM, the Europeana Data Model, and property graphs (Blanke, Bryant and Hedges 2013).

  2. Techniques for importing and combining existing data relating to manuscript histories.
    The existing data relating to the Phillipps manuscripts are scattered across numerous digital and physical sources, in multiple languages. They are, inevitably, in a variety of different formats and schemas, ranging from relational databases and MARC records to handwritten notes and card indexes. Capturing these data and aligning them to a common data model are complex tasks, which require multiple ingestion paths and crosswalks.

  3. The deployment of suitable software to manage the data and to support analysis and visualization.
    Suitable software is critical for a project of this kind. I will report on work I have done with two specific platforms: the graph database software Neo4j (Van Bruggen 2014) and the Nodegoat data management environment (Van Bree and Kessels 2015). I will also discuss the implementation process for the data model used to aggregate the provenance data used in this project

  4. Methods for visualizing and analyzing the data produced by the project, and for making them available for re-use by other researchers.
    I will look at a series of use cases and research questions related to the aggregated data, and will demonstrate how Neo4j and Nodegoat can be use to produce analyses and visualizations in response to these requirements. I will also discuss methods for linking the data produced by this project with the wider Linked Data cloud, in order to enable wider contextualization and analysis.  I will compare the results made possible by my software environment and data model with those produced by the Schoenberg Database of Manuscripts – a relational database which focuses specifically on manuscript provenance.
