We listened to your feedback and compiled highlights below from a variety of resources of user interactions including the UMLS Annual Report, 2020 Request for Information (RFI) about the UMLS, conferences, and customer service inquiries.
</p>
<p>
Please note, we ask all UMLS licensees to complete the Annual Report to meet the reporting requirement in the License Agreement for Use of the UMLS Metathesaurus. You may have requested a UMLS license for the use of the UMLS, SNOMED CT, RxNorm, the Value Set Authority Center (VSAC), or another terminology product or service provided by the National Library of Medicine. You may be using this information directly or indirectly via a vendor&rsquo;s application, such as medical coding software or an electronic health record (EHR).

Improvements based on user feedback
</h3>
<p>
<strong>
UMLS Terminology Services Redesign
</strong>
<br/>
In 2020, we updated the look and feel of the UMLS Terminology Services (UTS) website and the UMLS Metathesaurus Browser. The new web interface has the following new features:
</p>
<ul>
<li>
Browse code information from UMLS vocabularies
</li>
<li>
Search and browse hierarchies from UMLS vocabularies
</li>
<li>
Navigate broader and narrower UMLS concepts
</li>
<li>
Easily search for CUIs, AUIs, or codes
</li>
<li>
Find partial matches for any query
</li>
<li>
Updated look and feel
</li>
</ul>
<p>
In 2022, we moved the UTS from local servers to the cloud in order to improve overall stability and reliability of the application.
</p>
<p>
<strong>
UMLS API Authentication
</strong>
<br>
We have simplified UMLS API authentication. You can now
<a class="usa-link" href="https://documentation.uts.nlm.nih.gov/rest/authentication.html">
request data
</a>
by simply adding an API key to your data request.
</br>
</p>
<p>
<strong>
New UTS API endpoint
</strong>
<br/>
We have made a
<a class="usa-link" href="https://documentation.uts.nlm.nih.gov/automating-downloads.html ">
new API endpoint
</a>
available for automating downloads of RxNorm, SNOMED CT, and UMLS release files. Simply provide the URL and your API key.
</p>
<p>
<strong>
Python scripts
</strong>
<br/>
Several python scripts were added. An example is of our Crosswalking Vocabularies Using CUIs script which will crosswalk from a set of codes in one UMLS source vocabulary to a set of codes in another UMLS source vocabulary as long as the codes share a UMLS Concept. Visit

</p>
<p>
<strong>
UMLS Metathesaurus Precomputed Subsets
</strong>
In past years, we have required the use of MetamorphoSys to install and customize the UMLS Metathesaurus. For the 2022AB release, we are providing two ready-to-use precomputed subsets of the UMLS Metathesaurus that require no installation or customization.
</p>
<ul>
<li>
<strong>
UMLS Metathesaurus Full Subset
</strong>
(complete Metathesaurus data without any customization)
</li>
<li>
<strong>
UMLS Metathesaurus Level 0 Subset
</strong>
(Includes only level 0 source vocabularies. Level 0 vocabularies do not have any additional restrictions beyond the standard license terms)
</li>
</ul>
<p>
<strong>
UMLS Metathesaurus History Files
</strong>
<br/>
We heard from you that the process of having to pull historical data out of multiple releases is burdensome so we created three new files that contain historical data from the UMLS Metathesaurus. It was created in preparation of removing older sources.
</p>
<ul>
<li>
<strong>
Concept History (MRCONSO_HISTORY.txt)
</strong>
- This file contains all atoms, concepts, and codes that were dropped from the UMLS Metathesaurus MRCONSO.RRF starting with the 2004AA release.
</li>
<li>
<strong>
Relation History (MRREL_HISTORY.txt)
</strong>
- This file contains all relations dropped from the UMLS Metathesaurus MRREL.RRF file starting with the 2004AA release.
</li>
<li>
<strong>
Source Vocabulary History (MRSAB_HISTORY.txt)
</strong>
- This file includes a row for every version of every UMLS source vocabulary updated in the UMLS Metathesaurus MRSAB.RRF file starting with the 2004AA release.
</li>
</ul>
These history files are available from the
<a class="usa-link" href="https://www.nlm.nih.gov/research/umls/licensedcontent/umlsknowledgesources.html">

</ul>
<p>
<strong>
Orphanet
</strong>
<br/>
We heard your feedback that you wanted to see rare disease content, as a result we added a new source called Orphanet. NLM is excited to add Orphanet, a source of rare disease content, to the UMLS Metathesaurus. This addition is based in part on work done by SNOMED International and INSERM to produce a mapping between SNOMED CT and Orphanet. Orphanet will be updated biannually with each UMLS release.

<h3>
Example of tools that use the UMLS
</h3>
<p>
UMLS users have extended the functionality of the UMLS in a variety of ways by developing APIs, automation scripts, and natural language processing tools. You can find a list of these on the
<a class="usa-link" href="https://www.nlm.nih.gov/research/umls/implementation_resources/community/index.html">
UMLS Community web page
</a>
.
</p>
<p>
<img alt="examples of ways users use the umls" src="umlsusercontributions2.PNG"/>
</p>
<p>
Want to add your tool? Send a request to the NLM Help Desk (https://support.nlm.nih.gov/support/create-case/) with the subject line: "UMLS Community". Be sure to include a link to your source code so that other UMLS users can adapt your tool.
