Planteome Ontology WG Zoom Meeting

  • Date: Thursday Feb 18th, 2016
  • Time: 8:15am PST (GMT-8)
  • Connection details: Join from PC, Mac, Linux, iOS or Android: https://zoom.us/j/627445291
  • Attendees: AM, LC, CM, PJ, MAL, EA, GK, JE

Agenda:

Amigo 2.0 issues

1. Display of relations Currently, only the is_a, part_of and occurs_in relations are being displayed

  • Can we point the OLS and others like Bioportal to 'to-basic.obo'? Looks weird with the BFO and PLANTCHEBIROLE terms.

2. Propagation of annotations:

  • The annotations should be moving correctly through the relations in the graph, even if they are not displayed
    • CM: This is why the relations are being filtered. The old AmiGO would propagate everything, but now it can be set in the Planteome AmiGO 2.0 configuration. Generally, you only want the gene expression to propagate up through is_a and part_of

Need to look at the other PO relations such as has_part, participates_in, has_participant and for the TO, inheres_in and occurs_in and any others

3. Display of CO terms with dash or colon. did not discuss this week


Revisions to the Equivalence Axioms for the TO

  • Status of the BioCuration 2016 presentation and possible ICBO paper: Comparison of ontology mapping techniques to map traits (MAL)
    • bottleneck: needs of a collaborative revision of the design patterns (i.e. Equivalence Axioms)

Summary of the patterns in use in TO currently:

Need to clarify when to use occurs_in and when to use inheres_in in the equivalence axioms

  • Currently 'occurs_in' is used in several of the classes such as content and composition, but according to BFO, it is technically supposed to be used to relate a process (continuant) to a material entity or immaterial entity (independent continuant).
    • currently occurs_in is used incorrectly towards non-processes??

- 'Content' classes currently have these three patterns:

  • ‘amount’ (PATO:0000070) and inheres_in [CHEBI] (‘composition’(PATO:0000025))
  • ‘amount’ (PATO:0000070) and inheres_in [CHEBI] and occurs_in [PO]
  • ‘composition’(PATO:0000025) and inheres_in [CHEBI]
  • Comments from CM:
    • We need to have the first two since sometimes it is unspecified- i.e.- it just in the plant itself- problem is that there is no entity in the ontologies to represent this.
    • The BFO definition (see below) of "occurs_in" does not fit the current understanding of PATO.
    • In a trait ontology you are interested in looking at the changes in a trait over time, but you are looking at a limit case at an instance in time.
  • Definition:
    • b occurs_in c
    • b is a process
    • c is a material entity or immaterial entity
    • there exists a spatiotemporal region r
    • b occupies_spatiotemporal_region r
    • for all (t) if b exists_at t, then c exists_at t
    • there exist spatial regions s and s’, where & b spatially_projects_onto s at t
    • c is occupies_spatial_region s’ at t & s is a proper_continuant_part_of s’ at t
  • Paraphrase of definition: a relation between a process and an independent continuant, in which the process takes place entirely within the independent continuant
  • alternative term: unfolds in; unfolds_in; occurs_in

How to model count information: has_number_of vs amount

PATO vs. BFO

  • BFO wants to use has_number_of to describe count information, and PATO wants to use amount
  • BFO- annotate to the larger entity (having a number of)
  • PATO - smaller entity has an amount (or towards)


  • PATO has_number_of that inheres in the thing that is being counted. Instead of number_of petals inhering in
    • inheres_in the thing you're counting, occurs_in whatever larger entity
    • quality = amount, entity = seed, occurs_in pod
    • don't use relational qualities (eg: has_number_of)
    • occurs_in == towards
  • amount can inhere in the object being counted, where as has_number_of, is a quality of the larger entity
  • concentration: has increased concentration in a mixture, either increased amount in a mixture
  • has_number_of molecules, that's why has-number-of
  • We should annotate to the upper-level "molecular entity"; being consistent is more important than being correct (ontologically)

e.g. iron molecular entity

  • composition vs. amount: composition (PATO) cannot be used for non-morphology things (like blood, or sap)
    • composition is in the structure branch, and should be renamed "structural composition" or "structure composition"
    • - Need to open tracker for this
  • how to describe "number_of"

Discussion of PATO Composition

PATO_composition.png
  • PJ: suggestion to move composition out of subclass of structure, need to be able to describe the composition of entities such as xylem sap.
    • this would make it a physical object quality


Display of the Crop Ontologies in AmiGO2

  • Crop-specific names have been added to the rice, cassava and lentil files
  • Names should be in lower case



Visit to IRRI

  • Monday March 7th to Friday March 11th
  • Goals: TD revision and data annotation- MAL, and Leo will be working on trait dictionary
  • Austin- send me the contact info
  • all 3 - should be contacting each other as a group

Status of second year funding

  • Bioversity is getting impatient, PJ will follow up with NSF and find out
