kde-4.2.90 and nepomuk, good, bad,ugly?

[Rex Dieter]

Just threw virtuoso-opensource into kde-redhat/unstable repos.

If you've got kde-4.2.90 installed, and don't mind testing out nepomuk, 
install virtuoso-opensource , and report back.

good?  bad?  ugly?

Is there a description of what Nepomuk is? If I find the time to do
this test, I'd like to know what to look for.

It's the framework for tagging files. I got it, but I'm not too 
sure how to test it. At least nepomuksearch:/ isn't crashing 
Dolphin now.

It doesn't crash it here, either, but it doesn't find the files that I know 
exist (and according to systemsettings nepomuk indexing is definitely active)

Strigi indexing too? Strigi is what's used to find files which aren't
manually tagged, there's a separate checkbox in the Nepomuk settings to
enable it.

Hmm - this is not going to be helpful.  Akonadi was working until recently.  
On the 8th June I reported on this list that I now am getting kres-migrator (I 
think that's the name) failing on the netbook, and gave output.  I presume 
that it is since then that akonadi has not been working.  It does work on my 
F10 workstation, so I'll check that.

OK - checked.  Systemsettings now lets me configure which std.ics and std.vcf 
are to be searched. The Strigi part doesn't seem to exist any more.  Maybe I'm 
using the  nepomuksearch:/ command wrongly.  Example, please?

Akonadi is not directly related to this (well, Akonadi should allow its own
stuff to be searched through Nepomuk, not sure how far things are on that
front though), Strigi can be enabled in the Desktop Search section in
System Settings (where there's also the checkbox to enable Nepomuk itself).
I think Strigi also has an indexer for PIM data, so it'll find your PIM
contacts with a global search.

Ah yes - I'd forgotten that.  Well, Enable Nepomuk Semantic Desktop is 
checked, and there is no error message.  Enable Strigi Desktop File Indexer is 
checked, but "Strigi service failed to inialize, most likely due to an 
installation problem".

Anne,

Open '~/.kde/share/config/nepomukstrigirc'. Look at the '[main Settings]' 
section. What is the value of 'Used Soprano Backend'?

If it's not 'virtuosobackend', add  'Soprano Backend=virtuosobackend' to the 
'[Basic Settings]' section and try again.

All that's in there is

[General]
exclude filters=.*/,.*,*~,*.part
exclude folders[$e]=
folders[$e]=$HOME,/mnt/borg2_home/anne
index hidden folders=false
> What is the value of 'Used Soprano Backend'?

nepomukserverrc, however, has

[main Settings]
Storage Dir[$e]=$HOME/.kde/share/apps/nepomuk/repository/main/
Used Soprano Backend=redland
rebuilt index for type indexing=true
> If it's not 'virtuosobackend', add  'Soprano Backend=virtuosobackend' to

OK.  Guessing that I've now found it, I'll make that change.  Do I need to 
restart services?  I'd guess so.

I see also

[Service-nepomukmigration1]
autostart=false

Is this related to the akonadi problem I'm having, specifically the fact that 
akonadi keeps trying and failing to start?

I doubt it, nepomuk and akonadi are (largely) unrelated.

Sorry, Anne, I meant nepomukserverrc, but you figured it out. Yes, restart, 
Strigi should start and use the virtusoso backend. You should see a message 
saying that an automigrate is taking place, having changed the backend that's 
being used.

Don't think so. (But I don't know too much about akonadi.)

I spent 5 mins last weekend having a quick fiddle with virtuoso as the strigi 
backend. Tagging wasn't working at all. Keep an eye on ~/.xsession-errors. 
Lot's of logging there. Much weird bahvaiour - iodbc errors, cursor errors, 
dolphin hanging while re-indexing. It actually seems less stable than the 
sesame2 backend. But again, I did only spend 5 mins with it.

I've been busy away from the computers this afternoon, and atm the netbook is 
"Preparing system for upgrade", so when I'm in a position to un-cross my 
fingers I'll let you know whether it is now working. :-)

Thanks!  As Anne, pointed out, the config is
~/.kde/share/config/nepomukserverrc

But having changed it to
Backend=virtuosobackend

I still don't see virtuoso getting used (at least, I see no virtuoso-t 
process running)

it's a start though... I guess I have more hanging out in #nepomuk-kde 
to do.

Yes, sorry. That was off the top of my head - wrong file! ;)

'Soprano Backend=virtuosobackend', not just 'Backend=....' ?

Arg, mine contains actually
[main Settings]
Used Soprano Backend=...
and even after manually changing, it reverts back to
=redland

wtf?

Most likely you need to kill some running Nepomuk service, just like you
have to kill Plasma to edit or delete plasma-appletsrc effectively.

I considerred that.  Tried:  disabling nepomuk, logout/login, reset 
values, re-enable nepomuk

no fun.

Maybe it's a priority issue (i.e. Redland having higher priority than
Virtuoso for some reason)?

Hi Rex,

'Used Soprano Backend=...' gets updated  to whatever is being used as the 
backend every time the nepo strigi service is restarted. If you have libiodbc 
and virtuoso installed, add 'Soprano Backend=virtuosobackend' in the '[Basic 
Settings]' section of '~/.kde/share/config/nepomukserverrc'. (If the setting is 
not there it will always try to use 'redland' as that is the default). Then 
'System Settings->Desktop Search', uncheck the boxes for enable the desktop 
and enable string file indexer and apply. Then tick both the boxes and apply. 
Check nepomukserverrc to see if the it is using the virtuosobackend. ie. Used 
Soprano Backend=virtuosobackend'. If it still says 'redland', have a look at 
.xsession-errors to figure out why it's not working.

Is it possible that I have an essential file missing?  Can you list the files 
I should be checking for?  Thanks
