Nucleic Acids Research, 2007, Vol. 35, Web Server issue W25 Table 3. Projects where iHOP web services have been (or are being) used Project ORIEL DIAMONDS ECID COMBIO ENFIN (Enabling Systems Biology) Network of Excellence CARGO INB Description The CGI-XML API was developed in the context of this project, and it was integrated with other biological information resources. The iHOP SOAP interface was developed and applied to the dynamic extraction of proteins related with cell cycle in various genomes with special emphasis in Arabidopsis proteins. This information was used as input for the modelling approaches developed by the partners of this project. These projects and their tools (e.g. ENFIN Spindle proteins tool, CARGO framework) are currently using these iHOP web service APIs in diﬀerent biological and technical contexts. BioMOBY iHOP web services were funded by the Spanish National Bioinformatics Institute (INB), and published on the INB speciﬁc MOBY repository, integrated in the INB curated bioinformatics object ontology. The services will also be made available in the central MOBY repository of Canada.
