Hi Marc, Thanks for your prompt reply. Referring to the document you pointed me to, I created another R script within the organism package skeleton( an R script apart from zzz.R) and set cols, keytypes accessor methods. As part of annotation packages Bimaps are created in every annotation package. How do we use these Bimaps in these accessor methods? Am I right in thinking that these Bimaps are to be used in these accessor methods? Or those Bimaps have to be accessed only via get(), mget(), toTable() methods? Also, can you please let me know if there is any documentation available on how the GO views are created? I see there are seperate tables like go_cc, go_mf, go_bp, etc under Arabidopsis annotation package. Is it necessary to have go_cc, go_mf, go_bp, go_mf_all, like tables in the sqlite database for the customized annotation package I am creating? Will not just a single table for all GO annotations suffice? Thanks again for your time, Sashi > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor > >

You don't need them to implement select, cols, keytypes or keys. And they are really only still supported for the sake of older legacy code. The get, mget, and toTable methods are defined to help with bimaps, but you probably don't need to use these methods anyways. So it's very unlikely that you would even need to use bimaps let alone implement them. And the go view is just a SQLite database view. A view is sort of like a pre-canned database query that appears as a table. Our "go view" is really just the union of go_bp, go_mf, and go_cc tables. Those three separate tables allow us to still keep the different terms (from the different ontologies) as separate from each other in the database. But since we are using a view, we can also easily query all three of them (as if they were lumped together) WITHOUT actually duplicating all that data into another enormous table. And the performance for this is still great. You can read a bit about how SQLITE views are created here if you are curious: http://www.sqlite.org/lang_createview.html But if you are making an org package, why not just use makeOrgPackageFromNCBI?

It's good to know that BioConductor community is trying to move away from Bimaps and adopt cols, select, keys, keytypes methods for any sort of queries. Are Reverse maps that are part of Bimaps taken care by these accesors? As I understand, for older legacy code perhaps the makeOrgPackageFromNCBI is also still generating Bimaps and in near future, perhaps all the Annotation packages will just have a sqlite database and these accessors, defined. Am I correct? I had started by looking at how to build a sqlite db with some of the mappings we have and had not used makeOrgPackageFromNCBI function. My thinking was that having an understanding of sqlite db building will enable me to add any new mappings that are not part of NCBI. So, to summarize, for Annotation package development one approach is using makeOrgPackageFromNCBI() and the other approach is to make a sqlite db and then define these accessors, as given in the pdf you had linked me to earlier. And there will be no need of any Bimaps for the package development as such. Thanks for your time, -Sashi

Reverse maps are also unnecessary if you have defined those newer methods. So yes any new stuff you are developing should really just focus on those four accessors. The other stuff is just older stuff that you shouldn't ever need. And if you do need it, when we need to change something so that you no longer need it! We want to make it EASIER for people like you who are interested in exposing new resources. Science is hard enough already. ;) Marc > _______________________________________________ > Bioconductor mailing list > Bioconductor at r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor
