Concept Mapping and Semantic Linkages
Defining a shared data model and conceptual framework to build links across these disciplines, to help researchers integrate their data and ideas, is an important part in developing dataARC’s digital research tools. This task requires that we think about the ideas and conventions implicit in how each researcher models their own data, so that we can create a formal framework to clearly express the links between individual researchers’ shared ideas and questions. This formal framework is the dataARC concept map. The concept map is the product of much debate and discussion among the group, and will continue to evolve during the course of the project.
Ontologies like the CIDOC CRM and play a key role in cross-disciplinary data integration. Ontologies describe knowledge about a domain and document how concepts connect to one another. These structured descriptions of a set of inter-related concepts can be visualized as a graph - rather like a mind map. The DataArc community has developed a shared ontology, referred to in our documentation as the 'concept map', around the central concept of the 'changing landscape'.
To support compatibility and future integration with external projects, dataArc is connecting its concept map to the International Committee for for Documentation Conceptual Reference Model (CIDOC CRM). We’ve chosen the CIDOC CRM because of its active user community in the archaeological, cultural heritage, and historical domains, and the development of extensions such as CRMsci that support the incorporation of scientific observations.
We have also implemented limited mappings to relevant domain ontologies such as GBIF. Suggestions for cross-mappings to domain ontologies used in other domains connected to human ecodynamics are encouraged.
Individual concepts in our community-developed concept map are described in scope notes. These scope notes are authored and edited by multiple team members. Though short texts, they bring together interdisciplinary perspectives.
Our scope notes collection is a living document, hosted on github. Because ideas change and new voices enter our research community as it grows, we've chosen to take an open, discursive approach to writing the scope notes. Anyone interested in contributing a new scope note or suggesting revisions to scope notes can participate in the process.
You can view the current state of the scope notes and see their interconnections at our Scope Notes Repository. You can contribute new scope notes or suggest edits by forking the repository at github. You'll find the individual scope notes as markdown documents here. Submit a pull request with your contribution to get involved.
The concept map's connections drive the search results returned by the DataArc Data Discovery Tool. This search tool intentionally presents related results from other disciplines in addition to the results that respond to a domain specific query, and aims to explain why the results are relevant. You can see the current version of the dataArc concept map at work within the prototype tools that dataARC is developing here.
