The definition of groups in context of the movement roles project has been left open for interpretation and requires some classification. I would like to propose the following set of criteria for classification of groups within our movement and outside, that we are likely to encounter. My intention is to provide a starting point, from where the definition and classification of groups could be further refined.
The classification itself is based on logical options between any two sets of arbitrary groups.
There needs to be some formal classification of groups that we are likely to encounter. There are multiple approaches to how to classify such groups. The classification seeks to cover from the most basic congregation of individuals from within our movement to the largest chapters and even outside entities that might only share a common goal with the movement.
External vs. internal 
This approach aims to classify groups based on their position in the movement. Internal groups refers to groups from within the Wikimedia community, external groups might be complete or partial outside entities with aligned common goals with our movement. External groups can have affiliation and support from within the community but would be treated as outside entities. They might have outside an affiliation or other goals, not all of which are aligned with out movement.
Registered vs. unregistered 
These entities would be a sub-group under Internal groups. The definition would depend upon registered entities Vs. unregistered entities. The form of registration might differ from country to country. The global aspect of Wikimedia depends that the term of registration are left up to the groups themselves, the exact nature of which would require further refinement.
Official vs. informal 
This particular sub-group would account for official entities recognized by the foundation while the unofficial group would not require any such recognition. The unofficial group might remain unofficial for a multitude of reasons, from legal issues to personal preference, we might have groups that choose to remain as unofficial entities. Unofficial groups need to have their existence public with the rest of the community, either through mailing lists or wikis, and need to have support from their local community.

These groups should review and potentially approve parts of the MR work.
Formal groups 
These groups are incorporated and oversee projects in a certain part of the world, or are officially delegated authority by one of those groups. They have their own legal, financial, and reporting requirements

Group information 
To understand the current roles and responsibilities of different entities, we have asked each group some questions about their work and goals to map the movement, including:
