Who are we?

KarstLink  is an international cooperation to organize the online, machine-readable sharing of data on cavities and the karst environment. Initiated by  Wikicaves , the  FFS  and the  FSE , the work around the project will be carried by the UIS in  order to encourage as much as possible the participation of speleologists, scientists and managers of karst sites.

The project has set itself the objective of using standardized W3C tools relating to the  Semantic Web  in order to describe the environment of cavities and karst phenomena and thus offer all database managers a way to share their work without modify their infrastructure.

You can find out more details about KarstLink on  the UIS Wiki  .

After having defined formats and data models (ontology), see  ontology.uis-speleo.org  , this site hosts and aggregates all the  data  available in defined formats.

Use the site

This site and the underlying software are actively maintained; do not hesitate to send complaints and suggestions, either via a  github issue , or to [email protected]

Step by step navigation

Starting points:

• GrottoCenter.org API entry # 4
• a  Preserved Specimen from the GEB 

Then we click on the links. You can also use the buttons - icons "reverse links" and "centered view" (chronological view).

Research

Enter any words in the search field, examples:

•  Tham Phra => this returns the data including Tham OR Phra 
•  "Tham Phra" => this returns the data with the exact string in quotes
•  Tham AND Phra => this returns the data including Tham AND Phra 

(see more possibility:  documentation of Lucene search syntax )

• foaf: Person

(see  https://ontology.uis-speleo.org/ontology/  for a list of classes)

Access data

This site is a SPARQL standard server   . The access points are:

• / sparql  gives access to named graphs which here indicate the provenance
• / sparql2  overwrites all named graphs (no need for  GRAPH {...}  ); preferable for everyday use

You can use the generic  yasgui requestor  . By way of example, you can access the query used on certain pages by clicking on " Edit SPARQL query".  

Each display page gives access to the underlying RDF content (triplets) in the 4 main formats (check "expert mode").

Finally, there are other non-standard services designed to integrate data into other sites; see the documentation: 

https://github.com/jmvanel/semantic_forms/wiki/Application-development-manual#client-side-with-sf-web-services-api

Provide data

There are many possibilities: CSV formats with specific column names, RDF formats: XML, N-Triples, Turtle, JSON-LD.
