Thanks,

In GDCM it is a little bit mixed:

- VRs are up to date, including the newest 64 bits types SV, UV, OV, they were updated last year.
- UIDs were [updated to 2019b](https://github.com/malaterre/GDCM/commit/7faacda3c8f8232335eddd822529a8540d177a85)
- DICOM attributes dictionary is old, AFAIK [2011. may be some updates from 2017?](https://github.com/malaterre/GDCM/commits/master/Source/DataDictionary/gdcmDefaultDicts.cxx), also s. [Part6.xml](https://github.com/malaterre/GDCM/commits/master/Source/DataDictionary/Part6.xml),[gdcmTagKeywords.h](https://github.com/malaterre/GDCM/commits/master/Source/DataDictionary/gdcmTagKeywords.h), [gdcmTagToType.h](https://github.com/malaterre/GDCM/commits/master/Source/DataDictionary/gdcmTagToType.h), [gdcmTagToVR.cxx](https://github.com/malaterre/GDCM/commits/master/Source/DataStructureAndEncodingDefinition/gdcmTagToVR.cxx), not 100% sure

P.S. The dictionary is too old for me, so i updated to 2019b in my clone only. There are some nice _xls_ tools to generate dictionary, but several manual corrections are required and many files to generate/update, it is not a trivial task. Also one new _VM 2-4_ is in 2019b, i asked the maintainer [to help with](https://sourceforge.net/p/gdcm/feature-requests/43/), without response.

@mihail.isakov thanks for the input this is what I found in the Docs as well. The 2011 dictionary seems to work for me. However it’s always nice when things are current.

I believe, the dictionary is little newer, date in Part6.xml is 2011, but seems that it was updated 2017 to some level, not all files, but gdcmDefaultDicts, IMHO, must be OK, i hope. The question is very good, BTW, it is important.
