Thanks Lars,

I have tested Offline capability successfully and need to add describe two
sentences into the document.
"Once you shut down the browser before offline update, then you will lose
metadata.
Once you shut down the browser before uploading the offline updated data,
then you will lose these data."
I will recommended to use "Suspend" and "Resume" capability for note book
users to keep browsers up.
GIS test report will send by Cheburet, later.
    Best regards,
      Suzuki

Subject: [Dhis2-devs] DHIS 2 version 2.4 BETA available

Hi all,


we have made a preview of DHIS version 2.4 available here:

http://demo.dhis2.org

Username and password is admin/district. You can download the WAR file from
here:

http://dhis2.org/download/dhis-2.4-beta.war


There are two features we would like to get feedback on in particular:


1. Offline data entry:

Data can now be entered while being disconnected from the Internet.
You need to be online while logging onto the data entry module - the very
first time this will take a few extra seconds (7+ depending on the
connection) since all meta-data are downloaded and stored in your browser in
the background. Its cool, try it out yourself:

- Open the data entry module, select an organisation unit, data set and
period. Punch in a few data values. (Use your local IP address if testing
locally.)

- Disconnect yourself from the Internet. Notice how the system detects your
offline status and displays a notification.

- See how everything works as before: You can continue to expand, collapse
and select organisation units from the tree. You can select data sets and
periods. Forms are loaded as usual. You can continue to enter data values
and mark data sets as complete for as long as you want.

- Re-connect to the Internet. See the notification from the system
explaining that you have locally stored data, and click "upload" to send the
data to the server. If you have been disconnected long enough for the
session to time out you will be asked to log in again (without leaving the
page).

o Nice additional benefits are that everything is a lot more responsive and
that bandwidth usage is greatly reduced as most data is now loaded locally.

o There are currently a few limitations in offline mode: Data values,
completeness registrations and min-max values on the server are not
displayed in the forms and the validation and history functions are
disabled.

o Firefox will ask for your permission for DHIS 2 to store data locally,
please allow this.


All this hopefully has the potential to make the online deployment strategy,
with all its benefits, feasible for areas with patchy Internet connectivity
and power supply. Given a latop or generator, this means that record
officers can continue their data entry work throughout the day even if
Internet connectivity or power supply have gone down temporarily. Using the
myDatamart tool she can also do offline data analysis.



2. GIS symbol layer:

1. The menu system has had an overhaul: The left-side menu is gone and the
layer and map-view information has been put on the top bar to make it more
accessible and give more space for the map itself. Information about the
current selection for each layer is displayed in the right-side menu.
Map-views can be loaded into specific layers, making it possible to load
different map-views into multiple layers at the same time.

2. A new "Symbol layer" is available. (Sorry for the confusion - the current
symbol layer has been renamed to "Facility layer".) This makes it possible
to do thematic mapping where images/symbols represent the values rather than
colors. One use case for this is displaying weather data relevant for
Malaria outbreak monitoring on the maps - think weather forecast with suns
and rain clouds.

- Define symbols/images as regular "Predefined legend sets", make sure you
select "Image" as symbolizer rather than "Color" (we will add more symbols
later).

- Open "Symbol layer" from the top bar, layer section (4th icon from the
left). Select indicator, period and organisation units as usual.
Select your preferred legend set and click "Update".





We are hoping for your participation and feedback. The final 2.4 release
will be on Friday 26.



best regards,


the DHIS 2 development team
