<p>The NCBO Virtual Appliance supports [http://www.geneontology.org/GO.format.obo-1_2.shtml OBO] and [http://www.w3.org/TR/owl-features/ OWL] ontology formats but not UMLS in its native form. To bridge this gap, we have developed a project called [https://github.com/ncbo/umls2rdf/ UMLS2RDF] that transforms UMLS ontologies into OWL/RDF.</p>

<p>UMLS2RDF is a Python script that connects to a UMLS MySQL installation and extracts the UMLS ontologies in a format that the Appliance can work with.</p>

In particular '''this content''' is mostly at the '''[https://ontoportal.github.io/administration/ontologies/handling_umls/ Submitting UMLS Content page]'''.
 
 
<h3>Install UMLS MySQL</h3>
 
 
 
<p>To import UMLS ontologies, a local installation of the [http://www.nlm.nih.gov/research/umls/implementation_resources/scripts/index.html UMLS MySQL release] needs to be available.  Please refer to the [http://www.nlm.nih.gov/research/umls/new_users/index.html UMLS documentation] for instructions on how to install the UMLS MySQL distribution.</p>
 
 
 
<h3>Install UMLS2RDF</h3>
 
 
 
<ol>
 
<li>First clone the github project:<br/><code>git clone https://github.com/ncbo/umls2rdf/</code></li>
 
<li>Install the MySQL Python driver. We recommend to use <code>pip</code> for this:<br/><code>pip install MySQL-python</code></li>
 
</ol>
 
 
 
<h3>Configure UMLS2RDF</h3>
 
 
 
<p>UMLS2RDF has two configuration files:</p>
 
 
 
<ol>
 
<li><strong>conf.py</strong> where the database configuration (host,name,user and password) needs to be specified. Also the output folder.</li>
 
<li><strong>umls.conf</strong> where one can specified the UMLS ontologies to be extracted. This is a comma separated file with the following 4 fields:
 
<ol type="a">
 
<li>SAB</li>
 
<li>This is legacy. Any value works.</li>
 
<li>Output file name.</li>
 
<li>Conversion strategy. Accepted values (load_on_codes, load_on_cuis).</li>
 
</ol>
 
</li>
 
</ol>
 
 
 
 
 
<p>With <em>load_on_codes</em> the original source of the ontology will be used as strategy. The Class IDs will be constructed with the MRCONSO.CODE field. If <em>load_on_cuis</em> is selected then the strategy to transform the ontology will use CUIs to construct the Class IDs.</p>
 
 
 
<p>In our [https://github.com/ncbo/umls2rdf/blob/master/umls.conf configuration file], you can see the settings used by our production system. These are all the UMLS ontologies that are publicly available in BioPortal.</p>
 
 
 
<h3>Run UMLS2RDF</h3>
 
 
 
<p>Once the configuration files have the settings run the command:</p>
 
 
 
<p><code>python umls2rdf.py</code></p>
 
 
 
<p>Depending on how many ontologies are extracted the run time can range from a few minutes to four hours. This process is memory intensive and to transform the largest UMLS ontologies (i.e: SNOMED) one needs at least 16G RAM available.</p>
 
 
 
<h3>Upload files to the NCBO Virtual Appliance</h3>
 
 
 
<p>The output files will be located in the folder specified in <strong>conf.py</strong>. Use the BioPortal Web form available in your appliance to submit the extracted ontologies. <strong>IMPORTANT:</strong> The ontology format in the submission form should be UMLS.</p>
 
 
 
<h3>Hardware Considerations</h3>
 
 
 
<p>NCBO dedicates a fair amount of resources (powerful servers) to handle a good portion of UMLS ontologies. Some of the UMLS ontologies contain millions of classes. To import the largest UMLS ontologies (i.e: RXNORM or SNOMEDCT) Users will have to run the Appliance in a powerful dedicated environment with 8GB RAM and 5GB hard disk space available.</p>
