RxNorm Drugs A linked version of the NLM's RxNorm database that connects prescription drugs, ingredients, and NDC through RXCUI a concept unique identifier. RxNorm is a product developed by NIH’s National Library of Medicine. It currently interlinks 12 different drug vocabularies around a unique concept identifier. Due to licensing only six of the drug vocabularies are made available as part of the LODD cloud. This includes: Medical Subject Headings,, Metathesaurus FDA National Drug Code Directory, Metathesaurus FDA Structured Product Labels, National Drug File, RxNorm Vocabulary, Veterans Health Administration National Drug File

Links are provided connecting RxNorm to drug bank and to the UMLS.

A graph of some of the LODD datasets (dark grey), related biomedical datasets (light grey), related general-purpose datasets (white) and their interconnections. Line weights correspond to the number of links. The direction of an arrow indicates the dataset that contains the links, e.g., an arrow from A to B means that dataset A contains RDF triples that use identifiers from B. Bidirectional arrows usually indicate that the links are mirrored in both datasets. More on the interlinking methodology and statistics can be found on the Interlinking page.

The LODD datasets have been crawled by the SWSE Semantic Web search engine and can be accessed via a faceted browsing interface at [1] (Example query: Varenicline).

Most of the LODD datasets have also been integrated into the SPARQL endpoint of the HCLS Knowledge Base, see the wiki page of the HCLS KB for further information.

Bio2RDF Data Sets

The Bio2RDF project has published 40 biology-, gene- and medical-related datasets (altogether 2.3 billion triples). The datasets are available via SPARQL endpoints and as Linked Data. It is recommended that you use the Bio2RDF Java Servlet, and optionally download the databases for efficient personal use. Running your own instance of the OpenLink Virtuoso AMI for EC2 is also an option (and for basic URI resolution doesn't require the Java Servlet, although if you want advanced queries you should still download it and configure it to query your EC2 sparql endpoint).


Data Sets for the LODD Task

To complement the drug-related Web of Data build by the LODD effort, the following data sets could/should also be published as Linked Data.

The LODD effort is currently gathering more information about relevant datasets. See also Evaluation of LODD Data Sets for current evaluation results.
