OBO & OWL Files
Step 1. Find a compatible ontology file and download to your local desktop. Vyasa Layar accepts ontology files in OBO (.obo) and OWL (.owl) formats. For example, you can find OWL and OBO versions of your ontology through BioPortal.
Step 2. Click the "Ontologies" subsection under your "Data Catalog" menu, located on the left-hand side of your Layar home page.
Step 3. Drag and drop your ontology file into Layar. You will notice an upload status bar pop up on the left hand side.
Step 4. Once loaded, refresh the webpage. You will see your new ontology available in the list of ontologies!
Step 5. Click the ontology name to see the Ontology View for that ontology, with the terms, synonyms, and related metadata.
If you are creating an ontology from a table-based file format, such as .xls or .csv, 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.
