Structured Data

Data comes in many shapes and sizes. We carefully transform data that are important for a project into format that tools can work with. Our goal is to use the right tool for every dataset and project. This ranges from ready-made software, via internally developed generic components and frameworks, to complex, project-specific workflows. Data is valuable and should have a clear path to the archive. We provide that route and the means to create the accompanying metadata.

Datasets are becoming strongly interconnected: internally, but increasingly also externally. These connections are established, for example, on the basis of shared key entities (people, places, commodities..) and core vocabularies. This is particularly the case in the field of Linked (Open) Data. With Timbuctoo, our own Linked Data Store, we offer researchers a stable basis for storing their data. Lenticular Lens makes it possible to create and validate links between entities in different Timbuctoo datasets. Within the Dutch CLARIAH infrastructure, we provide the "I" (Interoperability) in FAIR-datasets using vocabularies as the semantic cornerstone.

The origin (provenance) of data is an important point of attention in the (digital) humanities. This information gives researchers who want to reuse existing data insight into the sources and processing steps, which creates the basis for trust in a dataset. To support this we have created a provenance service that developers can easily integrate and that records these data traces. Our next step will be to provide custom insights on these data tracks for different target audiences.

Software and Data

  • Lenticular Lens is a tool which allows users to construct linksets between entities from different Timbuctoo datasets (so called data-alignment or reconciliation). Lenticular Lens tracks the configuration and the algorithms used in the alignment and is also able to report on manual corrections and the amount of manual validation done.
  • Timbuctoo is a Linked Data Store, which is able to store large graphs. It provides a GraphQL API interface, which makes the schema of the graph easily available for interaction. ResourceSync support enables us to keep related indexes and access tools synchronized. Timbuctoo keeps close track of the provenance. It is the heart of an expanding toolset to deal with all aspects of linked data.
  • Procrustus is our forms framework, which we can easily adapt to any data source and tweaked for maximum usability.
