Because DxOPL does for now only read XMP/IPTC/EXIF and also export info in this matter on Tiff and Jpegs i try to be sure to understand it’s restrictions.(in order not to mesh up DxOPL’s readout and preset actions)
i understand that XMP is a sort off Standard, but in general it’s a textfile where command lines and information is stored to read by applications as DxOPL.
And as far as i know it’s a adding process when you run it through different applications who can write ina XMP.
What i not yet know is the route of a XMP file to DxOPL a thing to be considered?
Say if i use Fast Raw Viewer to create a XMPfile, which is basicly tailored for Adobe’s LR system as colortags and exposure corrections/ WB corrections and such.
As in the corrections done (you can do some initial corrections in FRV wile examining the RAW-file and culling) in FRV and i use XMP creation it stores those Adobe tailored commandlines in a XMP file.(i hope i describe it correct if not please correct me.)
Then i would run it through XNviewMP for adding keywords and such so DxOPL’s indexing and search function can use those information writen in the XMP.
What i like to understand is what does DxOPL with settings made by FRV about exposure compensation WB settings, , stars, colorlabels (Or overwrite the XNviewMP application in the second step all not recognised data made by FRV. and write only the info it can deal with in the XMP?)
some screen shots of xmp testing:
the settings in FRV:
xmp view of the made xmpfile:
looking in XNviewMP it reads those writings in XMP.
and also the adjustment corrections:
ok i add a keyword and nothing more.
XMP-file is updated by XNviewMP.
now i open DXO my editor:
would i see the WB correction and de rating and the keywords and the EV of +1? no colorlabel i think because it doesn’t have this.
when i open the folder it shows the DB info so i made a new image in folder “nieuw”
copied the rawfile and the xmp inthere no show:
re start dxopl:
(nothing) i am thinking there is a error inhere of v3.2.
tested it in a other version and WB: no change, Keywords, shown, EV not shown and to my surprise no 5 star rating.
only 3 star to create fresh xmp by FRV:
and rating visible:
so passed through.
now i close dxo and reopen xnvmp
add keyword and add 2 stars to 5.
it reads the change of 5 stars but where is my “keyword”?
back to xnvmp refesh thumbnail library.
(reading xmpfiles again.) waiting, waiting waiting.
viewing my info xnvmp doesn’t create a “dc” header/chapter when i add keywords.
i start to feel stupid or i am in a rabit hole …
XMP a standard carrier? yes as in the way a txt file is but in a standard information transport container? geesh i get confused.
