Plant Physiology Publication

RW and LC are working on a manuscript to submit to Plant Physiology. This will be a more detailed description of the changes made to the PO in the past year, focusing on restructuring of PAO. Will focus on how PO is now applicable to a wider range of plant species.

BS commented that the manuscript is quite long. No need to provide extra explanations if it will have to be cut out later. The idea was to have everything in this manuscript, then cut as needed, and some of the background material could go into the AJB manuscript.

Discussion items arising from manuscript:

• Last week, we agreed to use "type" and "term" in the way BS suggested based on the Hill et al. 2008 gene annotation paper, rather than using "class"

Type = A universal, represents the entity or stage/phase in reality.

Term = the thing in the PO that corresponds to a PO id.

From BS: In the database computational world, the word type is used, but they don't distinguish between the type in reality and the thing in the ontology, because they only need to describe reality in the computer. In our circles, the name or term in the ontology is a linguistic representation of the type, which is present in reality.

Term is used to refer to the thing in an ontology which includes a name, a definition, references, etc.

We can use the words "node" and "edge" to avoid

• Prefixing some of the term names with "plant" (e.g. plant cell, plant embryo)

CM:"So I see you've decided to prefix many terms with "plant". I don't think this is necessary (we decided this at the JAX CL meeting), and no other ontology does anything similar. I guess if this is just for the upper level terms (which should be hidden from view in most applications) then the user-unfriendliness doesn't matter. It's also a little curious as the terms that have the potential to cause confusion in a pan-eukaryotic context (epidermis, cuticle) are _not_ prefixed. I would recommend omitting all "plant" prefixes. For details on automatic assignment of obo foundry unique labels, see our paper from WOMBO/ICBO this year."

Do we want to add "plant" as prefix to terms like epidermis, cuticle, vascular system? Probably should be consistent.

Do we want to remove other plant prefixes?

RW: I think they make sense for the upper level terms, because they are only defined in terms of plants (e.g., a plant anatomical entity is an AE that is in a plant)

• Use of noun form in term names: Is it nb that it is consistent across the ontology? (We decided this at the POC conf call POC_Conf._Call_5-17-11#Items_arising_from_previous_meetings:.)

CM: "I would say "embryonic plant structure" rather than "embryo plant structure", the relational adjective form is far more common in other ontologies, but horses for courses.

Should we change this? It does sound better.

• The defense of the "portion of" prefix doesn't sound very convincing.

Current text: "Although the phrase “portion of plant substance” is not part of everyday language, that name was chosen, rather than plant substance, to clearly express that this class can include any portion of a plant substance (such as xylem sap) found anywhere in the world, be it all of the xylem sap in the world, all of the xylem sap in any whole plant, or just the xylem sap found in one particular branch of one particular plant."

Suggestions for better wording?

BS will edit the mansuscript or add comments/suggestions for this.

• The reflexive part_of case is interesting (trichomes). What is in the manuscript is 100% correct. However, it is worthwhile bringing this up on the RO list.

RW will send an email to the RO list.

• Never say "children" or "parents" if you can be more specific (subtype, part_of)???

We can say "is_a child" or "part_of parent" or "is_a descendent" if we need to, so there is no confusion about the type of relation.

• Should PAO and PGDSO should be referred to as branches, rather or as sub ontologies

We will refer to them as branches of the PO. The most current version of the manuscript does this.

• Use of "relation" versus "relationship": is there a rule about when to use these words?

They mean the same thing. We can continue to use relation.
