 ### Requirements
 The requirements of the Conceptual Mapping are extracted from two sources: (1) the analysis of current mapping languages, and (2) the limitations of current languages identified by the community. These limitations are referred to as [Mapping Challenges](https://w3id.org/kg-construct/workshop/2021/challenges.html), and are proposed by the [W3C Knowledge Graph Construction Community Group](https://www.w3.org/community/kg-construct/).
 
-The requirements can be found [here](https://github.com/oeg-upm/Conceptual-Mapping/blob/main/requirements/Requirements%20-%20conceptual%20mapping.xlsx), and are specified with an identifier, its provenance and related ontology construct. They can be also visualized [here](https://oeg-upm.github.io/Conceptual-Mapping/requirements/requirements-core.html). [Themis tests](https://github.com/oeg-upm/Conceptual-Mapping/blob/main/requirements/Themis_tests.xlsx) are provided along the requirements to validate them. They can be run with the [Themis online service](https://themis.linkeddata.es/) by uploading (1) the [ontology code](https://raw.githubusercontent.com/oeg-upm/Conceptual-Mapping/main/ontology/conceptual-mapping.owl) and (2) [tests](https://raw.githubusercontent.com/oeg-upm/Conceptual-Mapping/main/requirements/testsuite-themis.ttl) .
