SADI for GMOD is a collection of ready-made SADI services for accessing sequence feature data in RDF form. The services were developed as an add-on for the GMOD (Generic Model Organism Database) project, which is a popular toolkit for building model organism databases and their associated websites (e.g. FlyBase).

  • 2. SADI for GMOD: Background SADI (Semantic Automated Discovery and  Integration) • Standard for Web services that consume/generate  RDF • Motivation: automated integration of bioinformatics  data and software  GMOD (Generic Model Organism Database) • Toolkit for building a model organism database and  website • Collection of related open source projects: e.g.  Chado, Gbrowse, Pathway Tools   • Many sites use GMOD components: FlyBase,  BeetleBase, DictyBase, etc. 
  • 3. SADI in a Nutshell• to invoke a SADI service: o HTTP POST an RDF document to the service URI o e.g. $ curl --data-binary @input.rdf• to get service metadata:   o HTTP GET on service URL o returns an RDF document with service name, description, etc.  o e.g. $ curl• structure of input/output data is described in OWL o service provider specifies one input OWL class and one output OWL class• strengths of SADI o no framework-specific messaging formats or ontologies o supports batch processing of inputs o supports long-running services (asynchronous services) more info:
