Table-Based Files (.csv, .xls, etc)

Step 1. Add your ontology file to Layar using one of your connectors (or local upload).

  • The ontology file can be any table-based file (for example, .csv, .tsv, .xls, etc are all compatible).

  • The system currently does not detect multiple sheets within your file. If you have multiple tabs of tables within your file, please save each sheet as a separate file before uploading to Layar.

Step 2. Once uploaded, click the file of interest within Layar.

Step 3. Click the vertical three-dot icon on any of the column headers within the table.

Step 4. Select "Create Ontology".

Step 5. Give your ontology a name, and identify which column of your table will be used as the label for the parent nodes (what you will see when you later view your ontology). All other columns can be saved as synonyms for this primary label, or as individual properties, which will be viewable in each term's metadata card.

  • Note: Synonyms will be searchable through the Ontology Search Bar, but other metadata properties will only be searchable through an API query or filter capability.

Step 6. Click "Create Ontology"

Step 7. Your table will now be converted to a flat-term ontology, which you will be able to view right away!


If you are creating an ontology from an .obo or .owl file, please read the following documentation.

To edit and modify ontologies further, see "How to Edit Ontologies". This article will provide you with more information on the different capabilities available in Layar for you to edit your ontology.
