Agree.  And if each data source owner can provide their mapping to the standard target, e.g. using Bioportal's mapping functionality and the skos mapping relations (e.g. closeMatch, exactMatch), that'd be great, as the owner would understand their data source the best.

The above would pretty much take care of steps 1-4 in the article (Gather knowledge about sources, Gather knowledge about desired consumer (target) view(s), Identify semantic correspondences among sources and from sources to the consumer views, Create needed attribute transformations).

Steps 5,6,8 (Specify data combination rules, Create logical mappings from sources to consumer, Create and optimize an executable connection for the specific run-time environment) can be done maybe with standard semantic web ways like SPARQL?

Step 7 (Data cleaning) could be aided by reasoning-based logical consistency checking.

It'd be good to hear on this topic from the Bioportal and the Health Ontology Mapper teams.

hi all,

peter, nice article, it matches well my experience.

one thing to note is that, in this context, that the mapping is
(hopefully) a one shot deal that then can be used into the future without
much change, e.g. the bio* efforts that map to sequence database records.
also if one has a standard target that everything is mapped to, this also
helps.  my experience was mapping third party gene expression experiments
(data and annotation) to MAGE-ML.  then there was a standard mapping that
didn't have to change from MAGE-ML to our Rosetta Resolver application
which provided the UI.
