MIKE2:Alternative Release Methodologies
From MIKE2.0 Methodology
-> You are here: MIKE2:Alternative Release Methodologies
Alternative Release Methodologies are being investigated as a means to balance release stability and adding new content to MIKE2.0. Four potential models are being investigated, the approach currently being followed is the Hierarchy Model.
Release Methodology Models
Each of the potential Release Methodology models and their pros/cons are described below. Each model is effectively implemented through the same technology, but different governance techniques are applied to how content is managed.
The Open Model employs minimal protection controls on any content; the only controls put in place are to protect against vandalism. Any contributor can change any content. Basically this approach is the same as the model currently followed by Wikipedia.
The Hierarchical Control Model puts control of many Core MIKE2.0 Methodology pages into the hands of the Data Governance and Management Consortium so that only known members of the group can make changes to some articles. This the approach currently being employed.
Federated Control Model
The Federated Control Model is similar to the Hierarchy Model but federates control out to a wider community by creating "domain leads" in charge of content. Leadership roles are generally defined at the Solution Offering level.
The Branch Model creates an alternate article page when a core content page is protected. This model can be used in conjunction with other models.
At this time the Hierarchy Control Model is in beta and should continue to be tested as the user community grows. Extensions are being developed that will allow for a Federated Control Model to be employed and this will soon be used on a trial basis. Users may choose to employ the Branch Model - there is nothing in the current approach that stops an alternate page from being created. The open model is too unstable to use across all content and should not be used for any of the Core MIKE2.0 Methodology. It should, however continue to be used for other assets.
Applying these Techniques to Categories
The Release Methodology described above applies specifically to articles, but the same approach may be applied to categories. There may be case where it makes sense to restrict who can create certain categories (such as those used for maturity rating) but there is still a need to allow users to be able to freely create new categories as needed.
