POC-TraitNet Meeting 05-28-2010, 9:00 am, EDT New York Botanical Garden
Present: Ramona Walls (POC, New York Botanical Garden), Dan Bunker (Traitnet, New Jersey Institute of Technology), Farshid Ahrestani (TraitNet, Columbia University and NJIT)
Discussion Summary
One of TraitNet's mail goals is to develop a sematic web application that would allow users to access ecological datasets that are on the web. To do this they are developing a "functional trait ontology." This is currently focusing on plants, because there are far more plant trait databases. Plant plant functional traits includes plant entities (the physical parts of the plant = plant structures in PO) and plant characteristics (direct or derived measurements of plant entities made by ecologists/biologists).
They are aware of the PO and TO, but decided to develope their own ontologies for several reasons. For plant characteristics, they found that many of the terms in TO were too specific to crop organism or to specific experimental procedures, and they needed many new characteristics that would be appropriate for ecologists. The PO (plant structure) had the terms they need for their plant entity ontology, but at when they began working on their ontology, its structure was not suitable for their needs. After consulting with several ecologists/plant experts, they began working on their own ontology, using many of the terms from PO. There are more interested in part_of relationships that is_a relationships. They have run into many of the same problems the PO has been dealing with, like where to classify terms or how to define upper level terms.
Ramona gave them some background on the PO (how it originally united several individual species ontologies from model organisms, and is currently being revised to include all plants), showed them how to access annotations and talked about how scientists might use the PO, and showed them the current test ontology on the dev browser and how to access the PO on SVN. She also explained that the anatomy_test file is under active development and is constantly changing.
There was a discussion of whether or not TraitNet should use the PO as it is (once a new release is published) or use terms from the PO, but with their own structure. It was agreed that it would add power to both TraitNet and PO if the ontology was shared, since then users would have access to both genetic and ecological annotations. Since ecologists generally study a limited set of plant structures, and they would probably only need to use a subset of PO terms, and might consider making a PO-Slim (see GO slims for TraitNet.
They do not need the level of detail that the PO has, s
They would like to evaluate a newer version of the PO to see if the structure will work for them. If so, they will probably just adopt the PO, rather than have their own ontology.
Ramona gave them Pankaj and Laurel's names, and they said they would like to get in touch with Pankaj later, after returning from an NCEAS working group.
