This refactoring will never stop, will it? Just made the intrinsic
precision modern.

Refactor more metrics towards string paradigm

Few cases should now be left with symbols in use where strings should be
used instead.

Reinstantiate the richness of information view

The richness of information metric view is not accessible again. I had
to throw out a duplicate record selection partial.

Replace Rails jQuery gem with vendor files

On my newly updated Chrome 31 I get the annoying message that
event.returnValue is deprecated. For reasons unknown this is
not included in the current Rails jQuery gem. Hence, I have
downloaded my own copy of jQuery.

Actually it is version 2 I have addded. It is a lot smaller
and supports less browser versions.

Remove href attributes to stop anchor jumping

Apparently my previous solution did not work at all. Thus, I simply
dropped the href attribute altogether. The alternative is data-target
and this works good.

Create analyzer for richness of information metric

The analyzer for the richness of information metric takes more or less
the knowledge on which the whole metric is computed (document count,
occurrences of words and categorical terms) and prepares it for a table
presentation.

Fix link checker view

The problem with refactoring is that with every inherent change a
cascade evolves. So many files need to be updated that all do the
same. Can this be generalized?

For now I am taking the tedious way. The link checker view displays
the result again.

Implement analysis page for accuracy view

The analysis page has now been implemented for the accuracy view. For
this the analysis value per metadata record was extended.

Extend accuracy metric by measuring file size

The file size of a resource is a typical example where the accuracy can
be measured by taking the distance between actual file size and expected
file size.

I have added this type of measure to the accuracy metric making it
hopefully more useful. Both results are now presented in tables.
