Data Selection by BIRDQL Service

Data can also be selected with BIRDQL queries; Expert users can however modify queries by hand. Three query service are available:

1. curl -F upload=@your_bird.ql 'http://bird.u-strasbg.fr:8080/bird/bsearch?service=birdql'
   

2. http://bird.u-strasbg.fr:8080/bird/bsearch?service=birdql&query=your_birdql
   

   • Example:

     •  http://bird.u-strasbg.fr:8080/bird/bsearch?service=birdql&query=ID * DB Uniprot--WH DE contains "histone"--LM 10--FD AC,DE--FM FLAT
       

     • http://bird.u-strasbg.fr:8080/bird/bsearch?service=birdql&query=ID * DB Uniprot--WH DE contains "Helianthinin"--LM 10--FM FASTA
       

     • http://bird.u-strasbg.fr:8080/bird/bsearch?service=birdql&query=ID * DB Uniprot--WH DE contains "Helianthinin"--LM 10--FM JSON
       

3. BIRD-QL Editor (in pres).
   • User can use this engine for intensive computation, download [birdql cmd].
   • Till then you can test your queries on the star3-8 in the program /groupes/poch/dkieffer/test_tools/BirdClient/BirdConsole.sh ( or download here).

API JAVA - BIRDQL Client

The API is an Interface of programming which defines the way in which a data-processing component can communicate with another. The API Java of BIRD contains useful reusable classes by external modules of access to the databases. It has functions (methods) returning the data selected under various formats. The user of high-level can use the API to develop new functionalities exploiting of the data. It can also be used to make personalized graphic interfaces and Web Services. The codes Java below illustrate the exploitation of BIRD API. BIRDQL Engine doesn’t return data but just OIDs of selected records. The content of the record must then be searched by the API.

API BIRD

Import org.igbmc.bird.* Class ExampleUtilisationAPI {

 InterfactDB birddb  = new InterfaceDB(“my-bird”)
 // BIRD-QL
     String birdql = ” ID * DB UniProt
                     --WH OS contains "Mus mus"
                     --WH OC contains "Eukaryota" & not "Metazoa"
                     --FM OID”
 Vector OID=birddb.queryengine.run(birdql);  
 For { i=1 to OID.size()   }
  { // result treatment
    UniProt obj=(UniProt)birddb.getObject(OID[i]);
            ….
  }
