For a description of the workshop, see Plant Ontology Workshop, Botany 2012.


  • Introductions of presenters and participants
    • determine participants' needs and interests
  • Brief introduction to the principles and content of the PO.
  • Tutorial on how to access the various resources available through the PO website:
    • how to navigate the website

    • how to browse or search for ontology terms or annotations
    • how to submit feedback (including requests for new terms or revised definitions)
    • how to download and work with ontology and annotation files.
  • Discussion of ontology terms and definitions
  • Supplemental: Instruction will be available on how to generate association files for genomic projects interested in contributing and maintaining new PO annotations. Anyone who wants to contribute annotation files should contact us directly. See also Annotation_Association_File_Format.


This will be flexible, depending on participant's needs. We do not anticipate using the full three hours.

9:00 - 9:30 Introductions and assessing needs and interests of participants

  • downloading and working with files - ontology file and annotation files (only if people want to be able to do this)

Download page

Association files as spread sheets, from SVN

Working with annotation files

  • How to create an annotation file (with help from Phenote, if there is interest).

10:45 - 11:00 Break and re-assessment of needs

11:00 - 11:30 PO and images

  • Presentation of CUPAC images: How PO terms can be used to annotate diverse anatomical data from across all plant species.
  • Image markup software: SIA demonstration.

11:30 - 11:50 Flexible time

Will continue hands-on tutorials if needed, or have a discussion.

11:50 - 12:00 Wrap up


A slide show with an [ introduction to the Plant Ontology}.

Plant Ontology browser users' guide. Help on how to navigate the PO AmiGO browser.

The developers guide to SVN provides instructions on how to check out a copy of the PO's SVN repository. For individual users, it is probably easier to just download a copy of the file you want directly from the PO SVN site.

You can download the latest version of the PO in OBOF, OWL, or table format from our download page.
