Hi folks,
It would be great to have an OrganismDb package for
Drosophila.melanogaster, similar to Homo.sapiens, Mus.musculus and
Rattus.norvegicus.
While trying to do this on my own using the Homo.sapiens package as a
starting point, I found the most similar looking keys to relate
org.Dm.eg.db and TxDb.Dmelanogaster.UCSC.dm6.ensGene to be "ENSEMBL" and
"GENEID" though there's a ".1" tacked to the end "GENEID" which makes it
harder to supply the graphInfo object to OrganismDbi:::.loadOrganismDbiPkg:
!> key_ <- function(db, key) sort(as.character(
+ select(db, keys(db, key), key,
key)[[key]]))
> key_head <- function(db, key) head(key_(db, key))
> key_head(TxDb.Dmelanogaster.UCSC.dm6.ensGene, "GENEID")
'select()' returned 1:1 mapping between keys and columns

In other words, like Rattus.norvegicus, it might be good do add a UCSC
"refGene" TxDb package for dm6 as "ensGene" doesn't appear to be as good of
a candidate (at least without some ugliness)? I was looking at creating a
dm6 UCSC "refGene" TxDb.
You can use GenomicFeatures::makeTxDbFromUCSC() to create the TxDb. The
man page, ?makeTxDbFromUCSC, also has helper functions that display
available genomes, tables and tracks.
I'm not completely sure of the result, but
library(OrganismDb)
odb = makeOrganismDbFromUCSC("dm6", tableName="refGene")
might be most of the way there?

I imagine one would query the UCSC public MySQL
server and then do the SQLite conversion. Although the conversion to
SQLite seems a bit finagly as the datatypes differ between MySQL and SQLite
and I'm having a hard time finding a well supported tool to do it; I don't
want to introduce errors or harm reproducibility. What do you use for
MySQL to SQLite conversion? Or would it be more sensible for you
benevolent dictators to generate the package(s)?
