From the website:
EuPathDB Bioinformatics Resource Center for Biodefense and Emerging/Re-emerging Infectious Diseases is a portal for accessing genomic-scale datasets associated with the eukaryotic pathogens (Cryptosporidium, Encephalitozoon, Entamoeba, Enterocytozoon, Giardia, Leishmania, Neospora, Plasmodium, Toxoplasma, Trichomonas and Trypanosoma).
OK, other than being cited in the previous post about integration using ontologies, why is this relevant to topic maps?
Check out the web tutorial on search strategies.
Now imagine being able to select/revise/view results for a TMQL query.
It would take some work and no doubt be domain specific, but I thought the example would be worth bringing to your attention.
Not to mention that these are data sets where improved access using topic maps could attract attention.
