Recap on the “From Open Data Portals to Open Data-Ecosystems” webinar
Axel currently works on various topics regarding data management and ecosystems. At the moment, he and his team are focusing on developing machine-readable and decentralised standards for data publishing and processing in the context of semantic web and linked (open) data. Throughout the talk, he addressed the state-of-affairs in this field, stating that:
- Common data and metadata formats are in place;
- Ontologies are widely re-used (i.e. schemata);
- Scalable methods for distributed processing and querying are available; and
- Centre nodes are widely used to build knowledge around them (e.g. WikiData)
Though this is a good starting point for the creation of a data ecosystem, the lack of data links and the fact that the publication of best practices is not yet common remains a barrier. In addition, the uptake of open data is still fragmented and sectorial, yet it is a necessary step for open data portals to transition into open data ecosystems.
A proposed solution to this problem is the Open Data Portal Watch, designed by the WU Wien. The initiative is a tool for collecting and assessing metadata quality over time. By using knowledge graphs and linked data, this tool strengthens open data and forms a vital piece of the data ecosystem puzzle. Nevertheless, Axel stresses that going forward, open data portals, publishers and users need to also include closed data, mix top-down with bottom-up approaches, and work on a decentralised architecture to allow for these data streams.
