Most OWL formatted loads make use of the least complicated procedure to achieve an installation. However, it is a popular format and LexEVS offers some extensive options for customizing a terminology at load time. Therefore step by step instructions are provided for an OWL load.

Step

Action

1

Obtain an OWL formatted source.
The National Center for Bio Ontology (NCBO Exit Disclaimer logo ) hosts OWL formatted and other sources and downloads of some sources are available.
OWL formatted source list
Save the source to a local folder.

2

Load the source without options.
Load in Linux/Unix environments:

./LoadOWL.sh -in "file:///home/LargeStorage/ontologies/owl/amino-acid.owl"

Load in Windows environments:

LoadOWL.bat -in "file:///home/LargeStorage/ontologies/owl/amino-acid.owl"

Sample output on success:

3

Load source with options:
Some sources may not offer much in the way of information about the terminology. Since this information is often found in resources outside the terminology itself, LexEVS offers an option to load it in an accompanying manifest file.
This is an example of an OWL file with minimal metadata about the terminology:

and this manifest file allows the user to add appropriate metadata:

Manifest file construction is detailed in the administrative guide.
Loading in LInux/Unix

./LoadOWL.sh -in "file:///data/phont/LexEVS/test/resources/testData/camera.owl" -mf "file:///data/phont/LexEVS/test/resources/testData/Camera-manifest.xml"

Loading in Windows

LoadOWL.bat -in  "file:///data/phont/LexEVS/test/resources/testData/camera.owl" -mf  "file:///data/phont/LexEVS/test/resources/testData/Camera-manifest.xml"

 

Special considerations for OWL2 loads in LexEVS 6.x.    OWL2 offers some unique possibilities for authoring and representation.  Some terminologies contain a wide range of namespaces that need to be referenced within the code system in order for certain kinds of namespace based searches and hierarchy traversals to take place.   Other options for load alterations can be made via a preferences file which can set root nodes and enable loading of Annotation Properties as relationships via a "strict owl" interpretation of the source.
