[bika-dev] These 'modules' first Alfonso?

[lemoene <le...@bi...>]

  Hi Alfonso

    Stop me when this gets too much (or we can go off-list - but in
    public here we might get some useful feedback - are you there Jean;-)

Am not sure about your team's available capacity, but if you are going 
to dive into the Bika 3 code any time soon, I recommend tackling any of 
these semi-detached outstanding items first:

1. Pdf writing

    In Inkosi LIMS 2 pdfs are only used as results publication
    preference - client contacts may select it from amongst all the
    other publication preferences and receive their analysis results as
    pdf attachments to emails. Eventually, LIMS 3.1 say, we would also
    make it possible to save and email all reports as pdf.

    We used ReportLab <http://www.reportlab.com/software/opensource/>
    for Inkosi and would consider it in conjunction with pisa
    <http://pypi.python.org/pypi/pisa/> this time round for its
    Plone/Zope integration and forward looking approach.

2. Graphing

    In Inkosi, we use Zope's RenderableCharts
    <http://www.contentmanagementsoftware.info/zope/RenderableCharts>
    and Reportlab again, as well as Gary Strangman's stats.py for the
    stats calculations required for QC distribution curves etc.

    R <http://www.r-project.org/> is the most obvious improvement to
    stats.py. For their ease of integration with Plone, consider:

        Matplotlib http://matplotlib.sourceforge.net/
        http://www.scipy.org/Wiki/Cookbook/Matplotlib/Matplotlib_and_Zope

        PyChart http://home.gna.org/pychart/
        http://plone.org/documentation/kb/add-charts 

    Graphs used in Inkosi/Health 0.3:

        Analysis results over time per sample point/patient
        Reference results per analysis over time
        Reference results distribution
        % Relative error for duplicates

    See QC reports and graphs
    <http://www.bikalabs.com/helpcentre/manual/bikalims20/qc/qcreports>
    re the last 3 in the Inkosi manual.

3. Working time calendar

    Written up in the Inkosi calendar here: Bika Calendar Manual
    <http://www.bikalabs.com/helpcentre/manual/bika-calendar-manual>. It
    is currently only used to determine accurate turn around times,
    excluding non-working hours, weekends and holidays, but has to be
    approached carefully so as not to exclude future scheduling
    requirements:

        Scheduling sampling in Bika  Water, some of it recurring - say
        sampling the same river on a weekly basis. The calendar will in
        this case be used to simply trigger the automated creation of 
        Analysis request, Sampling rounds and instructions, and alerting
        Samplers to it.

        Most complicated and notoriously challenging: to predict
        accurate expected turnaround times for clients based on the
        loads of instruments and analysts. Bika 3.5?-)

See you on the hub!-)
