plugin development guide still refers to api pre 4.4 & misses crucial infos

[Malte]

In the PluginDevelomentGuide?, the main references for developers to get started, i noticed the following topics are yet undocumented (the list is incomplete):

• importmodels line (#840)
• "composite" is still used instead of "childs"
• a pointer to the windows issue when "building from source" would make thing more complete (#775)
• Paragaph "Consuming a service" is outdated since 4.4 (and services can also be consumed in a migration as of 4.5)
• no documentation of the index_mode_uris is yet available
• creating custom events in plugins (as of 4.2) is yet un-documented
• the facets concept and service is yet un-documented
• how and when to use Transactions is yet un-documented
• what are workspaces, sharing modes and acl (assign topics, create memberships, defaults), system workspace
• what are custom association types
• server side exception handling/error reporting facility

Just so we all know what new developers might not yet know about dm4-plugin development when starting their plugin and just so we all can keep track of the doc work undone.

• paragraph about using a migration.properties file

See #444. I added a reference to this ticket there.

I just updated the https://trac.deepamehta.de/wiki/PluginDevelopmentGuide to be not anymore extensive but compatible with 4.8.

I suggest therefore to close this ticket and move the parts on missing docs into #444. Those are:

• documentation of index_mode_uris
• creating custom events in plugins (as of 4.2)
• server side exception handling/error reporting facility
• usage of transactions
• the facets concept and service
• using association types and custom association types
• workspaces, sharing modes and all their defaults

I hope this helps.
So, if one would review the changes to the existing
