**3.2. Need to use open grid service architecture ogsa-dai for data access and integration**

Apart from the ubiquitous call for more functionality, bioinformatics projects with commercial users/partners are very anxious about the security of their data. The issue is further complicated by the lack of coherent security models with the evolving WS-RF and WS-I specifications which OGSA-DAI now supports. This issue needs to be resolved if bioinformatics projects with commercial users/partners are not to be deterred from adopting the product despite its utility. In contrast to the diversity of its data resources, a limited range of operations on these resources is typically required. For instance, one operation is to create a study data set by aggregating data from iterative searches of remote data collections using the same taxonomy object (representing a species or other group) as the search parameter [48].
