There are a handful of com.cohga.server.dms and a couple of com.cohga.client.dms bundles, they provide the support for document retrieval and upload, and are each pretty small.
- com.cohga.server.dms
- Base DMS API for retrieving documents attached to an entity, which can be used with anything that can provide a link to a document, not just our internal one.
- com.cohga.server.dms.core
- Base implementation that provides the required support for the above API. Using the API to retrieve documents, building the information required by the client, handing requests, etc.
- com.cohga.client.dms
- Provides the base client side support for retrieving documents attached to an entity. The buttons to retrieve documents for the selected entities.
- com.cohga.server.dms.provider.file
- A file system based document provider that can handle documents stored in a structure on the file system, It builds an internal URL that links to the files and provides that to the client.
- com.cohga.server.dms.provider.db
- A database based document provider that relies on a database table that contains links to documents.
- com.cohga.server.dms.upload
- The DMS upload API, it provides the API that something needs to implement to allow storage of documents.
- com.cohga.server.dms.upload.code
- The base implementation that uses the API to store the documents.
- com.cohga.client.dms.upload
- The client side of the base upload implementation. Provides the forms for uploading a document.
- com.cohga.server.dms.storage.file
- An implementation of the storage API that used a file system database to record the information about uploaded documents. It also implements the document download API so that uploaded documents can be retrieved.
- com.cohga.server.dms.storage.db

Only one of com.cohga.server.dms.storage.file or com.cohga.server.dms.storage.db should ever be installed, as they both provide the same function, just in different ways.
