Read/Write Solr managed resources

[mocobeta]

Solr allows to read/write managed resources (stopwords, synonyms) via REST API.

It may be possible to handle these resources as the framework's dictionary.
Scenario:

1. Download the resource (i.e., synonym list) from Solr via API using a (specialized) processor.
2. (optional) Merge the resource and other processing data.
3. Modify the resource using the framework's Web editor.
4. Upload the modified resource to Solr using a (specialized) writer.

As described above, I guess it should be possible by creating a customized processor and a writer.
If there are more suitable data flow or customization points, please suggest me.
