Thanks for the good work development team especially the new web API module.

> Hi all,
>
> DHIS version 2.6 is released. We have a long list of improvements:
>
> 1. A new Web API module which provides read access to most objects in
> the system and read access to data values and messages: All resources
> are uniquely identified by URLs and have a rich set of representation
> formats; currently HTML, XML, JSON and JSONP. The resources are linked
> and navigable meaning that you can easily move between related
> resources using hyperlinks (for instance from the list of data sets to
> one particular data set, then to one particular data element). Certain
> resources (map, chart, report, report table and resource) have a
> special view of the aggregate data (rather than the meta-data info)
> which can be accessed by appending /data to the URL.
>
> The primary purpose of the Web API is to make DHIS suitable as a
> platform for third-party software clients and systems such as Web
> portals, content management systems, dashboards and mobile device
> clients. It provides a machine-readable API from where such clients
> can retrieve the desired data over the well-known HTTP protocol,
> without need for any knowledge of the DHIS internal technologies and
> implementation. You can explored it here:

> http://apps.dhis2.org/demo/api/charts/j1gNXBgwKVm
> http://apps.dhis2.org/demo/api/maps/H6jRsZXfDAp
>
> A small demo on how reports, charts and maps produced by DHIS can be
> embedded in a Web portal can be found here:
>
> http://dhis2.org/portal
>
> A more detailed write-up of the purpose and context of the Web API can
> be found here:

> 2. Saved charts in data visualizer module: After creating a chart and
> data table you can now save it as a favorite by clicking on the
> "Favorites" button in the top menu, then on "Manage favorites". This
> makes it easy to later reload your chart and also put it on your
> personal dashboard in the dashboard module. Favorites can be saved as
> personal or system views (if user is authorized). This means that
> users can create their own personal charts without affecting the list
> of charts for other users.
>
> The old chart user interface in reporting module has been removed -
> the data visualizer module is now the place to create charts. Please
> note the new "Chart options" panel on the left menu - all options from
> the old charts are there but at the moment only implemented in the
> image  version of the charts (accessible from the dashboard). We will
> soon implement these options in the client-side charts in data
> visualizer module in order to make both versions compatible.

> 3. Anonymous events: The beneficiary module now provides functionality
> for registering anonymous events. Use-cases for such events are birth
> certificates, nutrition surveys and inpatient morbidity/mortality
> registries. Data for any number of data elements can be defined and
> registered for a single event (no attributes).
>
> Programs must be marked as "single event" and "anonymous" in
> beneficiary module. Under "Event registration" in data records module
> you can register the anonymous events. Start by clicking on "Create
> new event", then fill the entry form before clicking "Complete data
> entry".
>

>
> (Select e.g. the first facility in the tree, Ngelehun CHC.)
>
>
> 4. Organisation unit group set analysis in data mart and report table:
> The data mart engine now produces two new data mart tables for data
> element and indicator data aggregated by organisation unit groups. In
> more detail, for all organisation units there are records for all
> organisation unit groups. This feature has currently been implemented
> in the report table tool. You can include groups by clicking on
> "Toggle organisation unit groups" in the add new report table screen.
> We will implement support for groups in most analysis tools for next
> release. Please note that only groups which are members of a group set
> will be included.
>
> This feature is particular useful for doing analysis based on facility
> classification such as type and ownership; for instance you can now
> investigate the immunization rates in public, private and faith-based
> facilities within a province and see how they compare. It can also
> support scenarios where donors want to analyse and compare the
> performance of their implementing partners.
>

>
>
> 5. I18n: The user interface is now completely translated into French.
> This will be very useful for the upcoming DHIS implementations in West
> Africa. Thanks to Jason Pickering for managing this process.

>
> 6. Image maps: Map views from the GIS module are rendered and served
> as images (PNG fomat). This is useful when you want to easily embed
> maps in external Web sites. These image maps can be retrieved through
> the Web API.
>
> http://apps.dhis2.org/demo/api/maps/Y8dSQ3fH0Xe
>
>
> 7. Chart download in data visualizer: Charts can now be downloaded as
> image files in PNG format by clicking on the "Download as" button from
> the top menu and selecting "Image (PNG)" from the menu.
>
>
> 8. Data table in data visualizer: Data for the selected indicators,
> data elements etc can now be viewed in a data table (in addition to
> the chart). Simply click on the "Data table" button on the top menu to
> show the table, then click again to hide.
>
> http://apps.dhis2.org/demo/dhis-web-visualizer/app/index.html
>
>
> 9. Stable object identifiers: We have introduced a stable unique
> identifier (uid) for all objects in the system. This is useful and
> required for robust data exchange (rather than relying on identifying
> objects by names or other attributes which can be modified by the end
> user). These uids are used in the URLs in the Web API to uniquely
> identify all objects.
>
>
> 10. Scheduling: More options for scheduled tasks are now available.
> First, you can set which period types to include in the data mart
> tasks, which means you can now have e.g. bi-monthly and six-monthly
> periods in the data mart tables. Second, you can set the data mart
> export strategy, i.e. whether you want to have the system a) export
> data for the last 12 months every night, or b) export data for the
> last 6 months every night except Sunday then data for the last 6 to 12
> months every Sunday. The latter strategy will double the aggregation
> capacity of the deployment, given that the time lag is acceptable.
> Third you can set the lowest organisation unit level of aggregation
> for the organisation unit group based data marts - please note it is
> pointless to export organisation unit group data for the
> facility/lowest layer.

> 11. WMS support in GIS: A Web Map Service is a standard protocol for
> serving georeferenced map images over the Internet. To create a WMS
> layer, navigate to the GIS module and click the "WMS overlays" button
> below the layer tree in the top right corner. In the URL textfield you
> are supposed to enter the WMS resource url, e.g.
>
> http://iridl.ldeo.columbia.edu/SOURCES/.IRI/.Analyses/.CSMT/.Annual_Sum/X/Y/fig-+colors+-fig//antialias+true+psdef+/wmsfigmap
> . The layer textfield expects the title of the layer so look for the
> <title> tag in the WMS xml file.

>
> 12. Performance improvements all over the system: The network usage
> and load time for maps in the GIS module is down to approximately 1/3
> compared to version 2.5. The number of database connections required
> to retrieve reports and charts has been greatly reduced which means
> that the system will handle high user-concurrency better. Data mart
> generation time is down approximately 20 %.
>
>
> 13. Support for message notifications over SMS: Messages can now be
> delivered to the users' mobile phones through SMS (in addition to the
> DHIS inbox and e-mail). We will return with more info regarding
> configuration later.
>
>
> 14. PDF download: Dynamic attributes are now included in the PDF
> download for data elements, indicators and organisation units.
