In this paper we define a new algorithm to convert an input relational database to an output set of RDF triples. The algorithm can be used to e.g. load CSV data into a financial OWL ontology such as FIBO...

In this paper we consider how to integrate a simple and developer-friendly data model such as the property graph with more complex and less user-friendly data models such as relational database tables...

One way to answer business questions is to gather relevant data, integrate it according to business rules, and then populate a data warehouse in your favorite data store with the integrated information. If the warehouse is properly designed, and the source data is complete...

In this paper we show how to compute left-Kan extensions of set-valued functors with the venerable chase algorithm from relational data base theory. The chase constructs an initial model of a particular finite-limit theory associated with each left-Kan extension...

We take a popular position that AI systems are limited more by the integrity of the data they are learning from than by the sophistication of their algorithms. We also take an uncommon position that this limitation is not overcome by the data lake approach of cleaning data after it is loaded...

Using a simplified financial reporting example, we examine how traditional data warehouses are put together. We then propose an improved method for creating data warehouses: using the categorical query language CQL...

We consider the issue of multiple overlapping data models in the context of modern power grids. We present a methodology for specifying, managing and reasoning within multiple models of distributed energy resources (DERs, e.g., microgrids and generators)...

CQL is an open-source query and data integration scripting language that can be applied to common challenges in the field of computational science. It can preserve structure as it moves data from one database to another...

We describe a new model management approach based on algebraic specification following a survey of the field of model management...

Our approach to data integration is based on combining techniques from functional programming, category theory and database theory. We present formalism for schema mapping between databases using category-theoretic adjunctions...
