Hi :slight_smile:
Bouncing back on the improved image storage. Is the value type “image” supported by the mobile app yet? If not, is it planned?

Hi @Thomas_Warichet. It is already supported (image as value types)


Great news @mike on the cache issue of the capture app! For clarification, what does the funtionality check against when you talk about versioning?
Is it full metadata version increments or other (smaller) metadata changes?

Will there be a way to implement category combos with Tracker data elements?

Hi @Rasheed,
It would be nice with some more detail on the use case in mind here. Which data sources do you wish to triangulate?

We are also struggling to add dual date (English and Nepali) in ‘Date of Birth’ in Tracker.

HI @mraja, Here is the new Tracker Implementation Guide, and this is a link to the folder containing training materials from the new level 2 implementation academy

Hi @theo!
The version in question is a manually managed version in the maintenance page of your program:

When the version is increased, the web Capture clients will know and download all relevant data.

Hi @LauraLincks,
We have functionality to capture events within categories in the existing tracker capture app, and you might have tried this already? As this is being reimplemented in the new Capture app it would be great to get more info on your use case. Happy to spin off a thread on that topic.

Data capture by any tracker in health facility is sub-set of the whole information generated from registration and multiple clinical interactions. How do you identify the variables to which data to be captured during each encounter?? as it varies from country to country.

It is great to capture picture . But how do you manage the uniqueness of an individual who get services at different sites…to avoid duplications and scattered medical records of the individual?

Do we have multiple selection support available? I saw some screens showing the Combo box in the demo.

Hi @Neeraj_Gupta, if you mean multiple selection for optionsets, it is not available.

Currently Nepali calendar is not supported, as you know. We have started a bigger initiative looking at how we can handle multiple calendars throughout the solution. Would you need to do analytics based on Nepali periods as well, or are you mostly focused on registering data in Nepali format - to help users entering data?

HI @girma. You can define the uniqueness of an attribute at Organisation level or a whole system level.
