Naming the different objects in DHIS2 in a consistent, organised way facilitates your work as DHIS2 the work that we all do in our shared instance of DHIS2. It helps systems administrator when building a data collection tool or their related analytics. PSI’s naming conventions (also referred to as our nomenclature) define the way PSI classifies and names any object in PSI's DHIS instances. Using standard formatting helps objects in DHIS2 to be easily found and connected. This helps to readily identify what objects are for, organize and connect objects in different parts of the system, and ensure that we maintain standardized metadata. Standard nomenclature , or the it helps the thousands of users doing analytical work, trying to find the correct Data Element among our collection of thousands. Standardized naming convention also helps to avoid duplication of metadata objects.
The name should always be meaningful, even out of context (e.g. avoid " KE HCT - Confirmed referrals" but rather name the data element "KE HCT - Confirmed referrals for HIV care and treatment"). Ask yourself, would a person from another country with no knowledge of my project know what the object was meant to measure?
For regional/global projects that require metadata to be shared with multiple countries, the country prefix will be replaced by the project name or abbreviation. We also change the order of the prefix to [Project | Health Area] for regional/global projects., 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.
General naming structure
CI | HHH | PROJ | Measure 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)
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 Name
For Data Elements and Indicators, short names can be used at the time of analytics. You have a limit of 50 ch, but go for even less - about 25-30ch if possible. Your analytics will look much nicer !
Full Name: KH HIV NFP - Self-testing kits (STK) distributed
Short Name: KH HIV - STK distributed
