2. Additionally, this should be followed bymacro_log_feature( NEPOMUK_FOUND "Nepomuk" ...
see commented-out commands in top-level CMakeLists.txt.
3. These commented-out things should be removed, too.
4. Don't you also need soprano? Just guessing from the old commented-out code.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This is an important design issue:
You either need MemoryCollection or all these hashes, but not both. I'm still not convinced that you cannot avoid MemoryCollection at all, but if you use it, don't duplicate MapChanger.</pre>
</blockquote>
</blockquote>
<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There are two issues here.
First, it would be much better to have implemented an own QueryMaker that would translate Amarok's queries to Nepomuk's queries.
This would, of course, render MemoryCollection unneeded. However, we did not go that way in this project, and you can ask me (or phalgun) personally, if you want to learn the reasons.
Second, we tried to rely on MemoryCollection, and it didn't go very well. Main reason is that it mostly checks uniqueness by the uniqueness of titles (or title+artist for albums). However, it doesn't do this very reliably (or I didn't understand how to use it correctly), so some quirks did creep out here and there. So, we switched to nepomuk-uid-uniqueness, handled by NepomukCollection.
TL;DR: this is quasi-temporary solution as it is, as we will move to NepomukQueryMaker eventually. So let's leave these hashes where they are.</pre>

m_memoryColl->artistMap().contains( artistLabel ) (or something similar, ensire that the map is (const)-referenced and to copied during the call) and you get the answer (and proper instance)! Or, is calling it.binding( "artist" ) that expensive??
Same problems down from here.</pre>

Almost all of the code changes can be found in src/core-impl/collections/nepomukcollection/*
And a minor change in src/core-impl/collections/support/MemoryMeta.cpp
Code builds and after Nepomuk plugin is activated in the "Settings" dialog, Nepomuk Plugin comes into play and queries all the tracks in your machine. The query is not 'that' fast and might take several seconds depending on the number of tracks in your box.
IMPORTANT : Make sure Nepomuk is enabled if you want to give the plugin a spin. </pre>
