strong>IMPORTANT CHANGES TO i2b2 VMWARE IMAGE INSTALLATION<=

=20The i2b2 plug-ins will now be grouped together into an Eclipse feature. = The plug-ins that comprises the i2b2 Workbench will be packaged together as= the i2b2 core features. The core features include the following views in t= he i2b2 workbench.

Optional plug-ins will be packaged as =
features and will be posted to an update site on the i2b2 web page. Users w=
ill have the ability to easily add features (optional plug-ins) from within=
the i2b2 workbench by going to the help menu and selecting Add new feature=
s.
The tooltips that appear in Navigate Terms view have been enhanced to al=
low users to select whether or not they want to display the concept code in=
the tooltip and/or use the short tooltip.
A new Analysis view has been created that will allow users to view a bre=
akdown of the data in a bar chart.
Detailed information regarding the f=
unctionality of the Analysis plug-in and view can be found in the Analysis =
documentation included in this release.
Provided below is an outline of=
some key features of the Analysis View.
The new export data view will enable users to export data from one of th= e following tables.
=20
Detailed information regarding the fun=
ctionality will be provided in other documentation.
Note: This new view is an optional plug-in which can be added using the n=
ew "features" enhancement.
In version 1.4 the gridsphere is replaced with an admin component in the=
i2b2 Web Client.
Detailed information regarding the functionality of t=
he replacement of the gridsphere and changes to the PM services can be foun=
d in one of the following documents.
Roles based access has been added to the i2b2 Workbench. Users will be a=
llowed to perform specific tasks based upon their associated role. For inst=
ance, only users who have the role of DATA_DEID will be able to see de-iden=
tified data.
Detailed information regarding the functionality of roles =
based access can be found in the PM design documentation which will be prov=
ided in an upcoming release candidate.
In the new admin tool (PM) users can now choose whether or not they want=
to use ADS to authenticate against the active directory.
Detailed info=
rmation regarding the ADS can be found in the PM design documentation which=
will be provided in an upcoming release candidate.
A plug-in on the server has been added that will assist users in setting=
up custom plug-ins to work with the CRC.
Detailed information regardin=
g the functionality of the new server side plug-in can be found in one of t=
he following documents:
Users will be able to view an analysis breakdown of the concepts in Onto=
logy by toggling on/off the count in Navigate Terms View.
Detailed info=
rmation regarding the functionality of the new server side plug-in can be f=
ound in one of the following documents:
The roles that are given to a user may determine that they are only allo=
wed to view obfuscated (statistically anonymized) data. The patient counts =
that are returned to the client no longer represent true counts, but are "b=
lurred" by a random amount. If the same query is performed multiple times (=
perhaps to average the blurring effect) the patient is locked out of the sy=
stem.
The XML representing the patient data object (PDO) may be very large in =
some types of requests. If the server determines that the entire PDO cannot=
be served back due to resource limitations on the server-side, the server =
returns the largest number of patients it can satisfy, and information for =
the client to page through the remaining requests is included in the respon=
se.
The 1.4 release documentation can be found in a zip file located on the = i2b2 web page. This file includes documentation for the following:
=20
The following fixes were added to this release.
=20Zero patients will be returned when you run a query in which one of the =
concepts has a value constraint associated to one of the concepts. This pro=
blem only occurs if the type of value is a text value like "POSITIVE", "NEG=
ATIVE", "1+", "FEW", etc.. Queries will run correctly if the type of value =
is numerical or if the constraint is based on a flag such as "HIGH" or "LOW=
".
STATUS/RESOLUTION: This issue has been resolved=
. All queries now return the appropriate patients.
New parameters entered via Admin in the web client are not being saved t=
o the database. This is happening for all parameters (Project, User, etc).<=
br> STATUS/RESOLUTION: This issue has been resolved. U=
sers can now save parameters.
The "Project Description" and "Project Path" are not saved when entering=
a new project or editing an existing one.
STATUS/RESOLUTION:=
strong> This issue has been resolved. Project description and path are =
now saved.
A new "Project Key" is assigned every time you save an edit to the proje=
ct. This is a primary key and should not be edited.
STATUS/RESO=
LUTION: This issue has been resolved. Edits to a project no lo=
nger change the key.
When associating a user to a project you can select multiple roles. The =
problem is only one role is being saved even though several have been selec=
ted.
STATUS/RESOLUTION: This issue has been resolv=
ed. Multiple roles can now be saved for a user.
