hi tim,



thanks for your comments, i'll be interested to see how the Factors are
related to the assays, not sure how subclasses would work since one
actually needs different factor values for the factors, i.e. a time factor
can't tell you where in the time sequence the assay was done.



interesting about the protocols.  in implementing Annotare, the fged
sponsored open source tool for creating and editing MAGE-TAB documents, we
faced this same issue.  for various columns, like characteristics, species
and so on, we offer drop down selections based on ontology views from
NCBO.  when it came to protocols, you're exactly right, one has to consider
the position of the column in the mage-tab SDRF file in order to know what
type of protocol to use to populate the drop down.  i'm not even sure if
our UI guy has quite got it right yet.  but in the BioRDF use case where we
are looking at translating MAGE-TAB to RDF triples, since it is already
known, creating the triple associating the instance of a protocol to the
transition between an instance of material and/or data to the next instance
of material and or/data was trivial.  and if one is doing certain
investigations where it's the protocol that is being varied for a certain
step, this would be a tremendous loss to understanding/replicating of the
results to not have the link.



the other interesting case which i haven't seen anyone solve yet is the
fact that factors are duplications of characteristics of the samples or
protocol parameters but it is difficult to model that relationship.  i've
thought that might be some sort of 'is_a' relationship.



cheers,

michael

Hi Michael,



Thanks for your comments.  I appreciate them.  I've incorporated the one
about factors into a subsequent version of the model, and decided to pass
on the protocol relationships to data output, for pragmatic reasons,
although I am certain you are formally correct.

   - Factors were associated with the assays via a series of subclasses in
   previous versions of the model.  In this model I omitted the subclasses for
   improved readability but I should not have omitted the relationship with
   assays. I am adding them back at your suggestion.


   - Protocols we decided to leave formally unconnected to the data output
   in this model for simplicity. As my colleague Sudeshna Das points out,
   Protocols "... could be assay protocols, sample processing protocols or
   data processing protocols."  It is always a tradeoff and judgement call
   between increased formalization and additional burdens on the scientist to
   input the data.

Best



Tim

hi tim,

looks like you all are making good progress.

this is just from looking at the diagram, so this may already be covered,
but both protocol and factor are also related to other concepts.

protocols would be associated with 'has_output' and 'computed_from', and
there would be factor values associated with each factor of the study and
each assay would be associated with a set of factor values, one pre factor,
e.g. for dosage and time factors an assay might be associated with 1mg and
10 seconds.

also, is there any desire to track sample processing?

cheers,
michael
