Naming the different objects in DHIS2 in a consistent, organised way facilitates the work that we all do in our shared instance of DHIS2. It helps systems administrator when building data collection tool, or the it helps the thousands of users doing analytical work, trying to find the correct Data Element among our long collection of thousands. Standardized naming convention also helps to avoid duplication of metadata objects, and re-utilization when appropriate.

General principles
Simplify and shorten names whenever is possible
keep them meaningful
Always provide context.
Pay particular attention to Data Elements and indicators, as they are exposed in analytics and affect the rendering of the chart/ table.
Naming principles for Data Elements and Indicators
It should not be based on how the data is collected
It should not mention the frequency (by month, this year..)
“Number of” is unnecessary / redundant
Name and Short Name should be for data output (analytic)
Form Name is for data capture
General naming structure
CI | HHH | PROJ | Object Name |
Health Area acronym (2 to 4 letters) | Project acronym | Data collection dimension name (brief description) |
Examples:
KH HIV NFP - Self-testing kits distributed (a data element)
KH HIV NFP - Facility Monthly (a data set)
KH HIV NFP - Test type (a category combination)
Component | Meaning | Notes |
|---|---|---|
KH | Cambodia | In DHIS2 we always use the country 2-ISO code. Not required for global projects. |
HIV | Human Immunodeficiency Virus | The health area - see list |
NFP | New Frontiers Project | Optional - if the data must be collected only for that project |
Self-testing kits distributed | The measure in question | be as concise as possible. |
Short

Names
For Data Elements and Indicators, short names can be used at the time of analytics. You have a limit of 50 ch, but go aim for even less - about 25-30ch 30 ch if possible. Your analytics will look much nicer !
Full Name: KH HIV NFP - Self-testing kits (STK) distributed
Short Name: KH HIV - STK distributed

...
Codes are optional for all objects, but may assist in providing an additional mechanism for sorting objects and importing/exporting metadata and data associated with the object across servers. Specific nomenclature for organisation unit codes is described in the organisation unit standard.
General principles for codes:
Never use spaces
Keep length consistent, if possible
DHIS2 Object | Code Convention | Code Example |
|---|---|---|
Data element | [CORE/ISO2]_[3 letter intervention area code]-[2-4 letter project/program code]_[(TRK)]_[123] | CORE_MAL-RDT_003 CD_MAL-RDT_038 |
