On the way to an improved metadata display:

(1) weird file names that can be simplified without problem
- '__', '...', '_-_'
aaarjel_faaroe__raettad_oppgave....doc.xml
a_saaran_gaerja_-_biejjeste_beajjan.doc.xml
 ==> aha, there a special characters in some filenames: bug

(2) bug: files right in the main category 

bc_sma_ficti.txt:a_saaran_gaerja_-_biejjeste_beajjan.doc.xml
bc_sma_ficti.txt:aaarjel_faaroe.doc.xml
bc_sme_ficti.txt:aigin_lavra_-_olles.doc.xml
bc_sme_ficti.txt:aikio-sme-001-005corr.txt.xml
bc_sme_laws.txt:lov_om_psykisk.nob.doc.xml


(3) bug: inconsistent naming (cip has corrected this type of inconsistencies in the freecorpus)
bc_sma_admin.txt:other
bc_sma_news.txt:other
vs.
bc_sma_bible.txt:other_files
bc_sma_facta.txt:other_files
bc_sme_bible.txt:other_files
bc_sme_facta.txt:other_files

(4) bug: wrong grouping: avvir and MinAigi have obviously to different dir on the same level yet they
    belong to one and the same group "data stemming from ..."

bc_sme_news.txt:avvir.no
bc_sme_news.txt:Avvir_xml-filer
bc_sme_news.txt:MinAigi
bc_sme_news.txt:minaigi.no

(5) inconsistent info in metadata (I hope we will not need all but about firstname and lastname?): 
      <person firstname="" lastname="jf" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="joseph Fjellgren" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="jf" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="Johan Göransson" sex="unknown" born="" nationality="en_US"/>
      <person firstname="" lastname="Holodeck" sex="unknown" born="" nationality="sv"/>
      <person firstname="" lastname="see" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="jf" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="SUPERVISOR" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="ta" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="sbp" sex="unknown" born="" nationality="en_US"/>

      <person firstname="" lastname="Sameskolen" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="Bra Da Boo" sex="unknown" born="" nationality="no"/>
      <person firstname="" lastname="Administratör" sex="unknown" born="" nationality="en_US"/>
      <person firstname="" lastname="Språk Elgå" sex="unknown" born="" nationality="en_US"/>
      <person firstname="" lastname="Margareta" sex="unknown" born="" nationality="sv"/>
      <person firstname="Lena" lastname="Kuoljok Lind" sex="f" born="" nationality="swe"/>
