Hi,

in fact this is an issue. However, the different storage backends are dynamically initialized on demand by the corresponding factory. I.e. you only need the specific installed dependency if you really want to access for instance a Subversion repository. Nevertheless, we have to document it and also to adapt the build script to provide those bundled distributions. Could you please file a corresponding bug report?

Betreff: [Datafinder-team] requirements/dependencies

Hi,

I've just seen another development dependency (pysvn) added to the wiki here:

https://wiki.sistec.dlr.de/DataFinderOpenSource/RequiredDevPackages

This got me thinking, as we've hit a similar point in another project I'm 
participating (Griffin). DataFinder now has got a large and growing list of 
dependencies, but not everybody needs to satisfy each and every one of them. 
Many of them are dependent on the type of storage backend used by DF (e. g. 
boto for AWS, PySVN for SVN, pythonwebdavlib for WebDAV, ...).

My suggestion is as follows, and I'm hoping to get some constructive 
discussion out of this:

 * Split off a core DataFinder application without any data store backends.

 * Make all (meta-) data store backends into plugins, that can be developed
   and hosted separately, even if they live under the same project.

 * For ease of use, a DataFinder *distribution* can be created that ships
   with the/a default plugin (most probably WebDAV).

 * Split off the documentation (e. g. dependencies, build/install/configure
   notes off to be specific for each plugin.

 * Document for each plugin how it is to be integrated/used with DataFinder.

Any comments?

Guy
