The whole Semantic Web rests on a little thingy: ,[object Object]
Subject   predicate  object   graph Quads
ntriple format Resource or Blank Node Only Resource Resource Literal  Blank Node (?:(?<=<)[^>]+(?=>))|(?:amp;quot;(?:(?:[^amp;quot;]|(?:amp;quot;))*)amp;quot;[^.  ]*)|(?:_:[-_a-zA-Z0-9]+)
As RDF/XML

DrugBank A repository of almost 5000 FDA-approved small molecule and biotech drugs.  Contains detailed information about drugs including chemical, pharmacological and pharmaceutical data; along with comprehensive drug target data such as sequence, structure, and pathway information.
LinkedCT: Clinical Trials Up-to-date information for locating federally and privately supported clinical trials for a wide range of diseases and conditions. It contains 81,571 trials sponsored by the National Institutes of Health, other federal agencies, and private industry ClinicalTrials.gov receives over 40 million page views per month 50,000 visitors daily.
Diseasome Publishes a network of 4,300 disorders and disease genes linked by known disorder-gene associations for exploring all known phenotype and disease gene associations, indicating the common genetic origin of many diseases. The list of disorders, disease genes, and associations between them was obtained from the Online Mendelian Inheritance in Man (OMIM), a compilation of human disease genes and phenotypes.
DailyMed Published by the National Library of Medicine, and provides high quality information about marketed drugs. DailyMed provides much information including general background on the chemical structure of the compound and its therapeutic purpose, details on the compound's clinical pharmacology, indication and usage, contraindications, warnings, precautions, adverse reactions, overdosage, and patient counseling.
Sider Contains information on marketed drugs and their adverse effects. The information is extracted from public documents and package inserts.
