File system folder structure using type-namespace-id structure¶
Winery’s data is stored in a a file system ADR-0001. The contents of the repository should be
Folder structure using type-namespace-id
Everything in one folder. Hash-based storing similar to git.
Chosen Alternative: Folders subdivided in type-namespace-id
The final file system layout itself is documented at RepositoryLayout.
Everything in one directory causes many files listed and thus humans will have difficulties to find the right file.
The folders in the top level are the TOSCA “components”, e.g., Node Type, Relationship Type, Service Template, …
The second structuring element are namespaces. Namespaces are an established method to avoid naming conflicts and are a structuring element. TOSCA is an open system and everyone can create Node Types. One has no global control which names are given to Node Types. Thus, there might be two different Node Types with the same name. The namespaces provide a natural structuring and Winery reuses this idea.
The third structuring element are the ids of the respective definitions child (type, template, …): Each element has an id contained in the respective namespace. This id can be directly used as folder name.
Within each folder, the component-specific information is stored.
Windows cannot create directories named
Therefore, the names have to be encoded so that an appropriate folder can be generated.
