= LifeLines Catalogue meeting 2011/01/23 =

Basic features:
* On front page summary of lifelines + how many individuals
* per measurement: description, dataType, unit (all in English)
* Seperate catalogs for panels: children (<18), adults, elderly(>65).
(Of course largely overlapping.)

Big todo: create mock-up of new catalog user interface.

New major features required:

== Protocols ==
We want capability to add more details to protocols: hyperlinks to
attached files (SOPs, publications)

Implementation:
* Use MolgenisFile with an xref to Protocol
* Show in the user interface as download link

== Derivates ==
Derivate is a value that is derived from one or more other values
using some protocol. For example
* BMI: derived from length and weight using calculation
* blood pressure: derived from 10x blood pressure taking average of last 10
For each derivate we should define the 'protocol' and optionally a 'formula'.

Ideas for implementation:
* we should look into ComputeProtocol to encode the derivation protocol
* then this is unambiguous using protocolApplication

== Verification ==
Verification is the procedure used to correct erroneous data entry.
* For each Measurement we want to know if it is 'verified' = 'NO, NA, YES'.
* Each Measurement can have multiple verificationRule explaining how
verification is done (describing how the rule works).

Ideas for implementation:
- create a Measurement 'isVerified' and then report each verification via
Value(target=MeasurementX, feature=isVerified, value=NO)
- create new Feature called 'VerificationRule' with an xref to Measurement

== Protocol details ==
Verification | checked | how
Can be multiple verifications.

== When will the protocol be applied ==
We need an additional field to record at what times the protocol will
be applied.
For example: 'baseline', '5 years', 'yearly'.

Implementation:
- ??? I can imagine we use 'workflow' for this? Each workflow is then
the complete set of protocols...

== Download of selected measurement ==

Instead of 'order' people just should be able to download
* as PDF or Excel
* we log all downloads (using existing 'order' tables)
* for the admin we can then make a plot showing how many times a
measurement was selected

== Ideas for future versions ==
* counts per data item
* versions of the catalogue
* some barchart on how many data items are ordered per request (so
what items are popular).
* What kind of tools is used to measure bp, how old, where can you
order materials, (sample tracking?)
* measurements may not be orderable because discontinued
