Query environment |
Open http://185.23.162.165/. Register as a new user (recommended), then create a new project; start by choosing some example project (e.g. mini-University or Scholarly data). It is possible also to login as demo@lumii.lv/demo123 to a public sandbox environment (to be discontinued in the future). Check out the code to set up the tool locally (Docker-based running options available, as well). |
||||||||||||
Quick intro |
The query environment for every user is organized in projects. The project relies on data schema for name completion and SPARQL generation,
and SPARQL endpoint connection for query execution. Every project consists of diagrams; there can be single or several queries in a diagram. An initial user manual is available. The query notation presentation over hospital data contains a wealth of query examples. The example data schemas and schemas to access some popular SPARQL endpoints are in Data schema store. |
||||||||||||
Selected data schemas and projects |
Upload a schema or entire project content to a created project environment.
Check data schema store for further examples. |
||||||||||||
Data schema retrieval |
Read more about data schema retrieval, check out the code. Use data schema retrieval service to analyze custom data endpoints and to retrieve data schema from an OWL ontology. Check Data schema store for schemas of Linked Data endpoints. |
