## STEP 1: make function to process metadata into AHMs
## This function will return the AHMs and takes no args.
## It also must specify a recipe function.
makeinparanoid8ToAHMs <- function(currentMetadata, justRunUnitTest, BiocVersion) {
    baseUrl <- 'http://inparanoid.sbc.su.se/download/current/Orthologs_other_formats'
    ## Then make the metadata for these
    meta <- .inparanoidMetadataFromUrl(baseUrl, justRunUnitTest)
    ## then make AnnotationHubMetadata objects.
    Map(AnnotationHubMetadata,
        ## AnnotationHubRoot=meta$annotationHubRoot,
        Description=meta$description,
        Genome=meta$genome,
        SourceUrl=meta$sourceUrl,
        SourceVersion=meta$sourceVersion,
        Species=meta$species,
        TaxonomyId=meta$taxonomyId,
        Title=meta$title,
        RDataPath=meta$rDataPath,
        MoreArgs=list(
          BiocVersion=BiocVersion,
	  SourceType="Inparanoid",
          Coordinate_1_based = TRUE, ## TRUE unless it "needs" to be FALSE
          DataProvider = "Inparanoid8",
          Maintainer = "Marc Carlson <mcarlson@fhcrc.org>",
          RDataClass = "Inparanoid8Db",
	  DispatchClass="SQLiteFile",	
          RDataDateAdded = Sys.time(),
          Recipe = "AnnotationHubData:::inparanoid8ToDbsRecipe",
          Tags = c("Inparanoid", "Gene", "Homology", "Annotation")))
}



## STEP 2: Make a recipe function that takes an AnnotationHubRecipe
## object.
inparanoid8ToDbsRecipe <- function(ahm){
    
    inputFiles <- metadata(ahm)$SourceFile 
    dbname <- makeInpDb(dir=file.path(inputFiles,""),
                        dataDir=tempdir())
    db <- loadDb(file=dbname)
    outputPath <- file.path(metadata(ahm)$AnnotationHubRoot,
                            metadata(ahm)$RDataPath)
    saveDb(db, file=outputPath) 
    outputFile(ahm)
}




## STEP 3:  Call the helper to set up the newResources() method
makeAnnotationHubResource("Inparanoid8ImportPreparer",
                          makeinparanoid8ToAHMs)
