Term | Definition |

Module | Modular programming is a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality. |
(Software) Package | A collection of functions written in a single language bundled with additional content like documentation, unit test, sample data etc. Source: https://en.wikipedia.org/wiki/Package_development_process |
Component | An individual software component is a software package, a web service, a web resource, or a module that encapsulates a set of related functions (or data). Source: https://en.wikipedia.org/wiki/Component-based_software_engineering#Software_component |
Sources | Technical source code, structures and definitions of an IT solution |
(JLN) Business Process |
|
Functional Unit | An interchangeable unit that provides a piece of business functionality |
(Software) Repository | A storage location for software packages & other technical sources Source: |
Key Questions
How to find a wording which is clear and prevents misunderstanding and allows for a common language between business (implementers) and technical (developer) people?
How to achieve an up-to-date documentation of the architecture and it’s features (modules) which satisfies and links the needs of implementers and developers

Describes “Modularity” as Modularity (and its integration counter-part) is considered at 3 distinct levels:
… Software Component and Entity levels modularity are fully in the scope (controlled by) of openIMIS. openIMIS is built modular "from the core on": even low level features (like login,...) and central features (like Insurance Scheme management,...) are built as a plugins of a core platform. The core platform provides generic components (building blocks) to be used by / particularised in the various plugins and is split in 3 layers:
Although openIMIS is an assembly of components (themselves assemblies of plugins), deployments of openIMIS doesn't impose a distributed deployment. The choice of isolating the various (server-side) components to dedicated infrastructure is taken according to each project's needs. Within a project, scaling up by distributing components as the load increases is a very standard (and easy) operation:
Plugins are documented in openIMIS Modules.

| In openIMIS, (nearly) everything is a module: even "low level" (and mandatory) features follow this principle. … Plugins (can) provide several types of archetypes, dedicated to the various openIMIS layers: openIMIS Mobile FE, openIMIS Web FE, openIMIS Online BE, openIMIS Batch BE,... openIMIS can be deployed with an extra layer dedicated to implement a FHIR API, based on openIMIS core (base) modules.
@Patrick Delcroix in the comments: Here my point of view on the module list details in 4 groups (core, business...) The module with * leading are not found in JLN IT core
