publication_type and dcetype
[ OK: Now that I can get hello_world to work, onto the real problems...]
I'm still learning my way around the calibre code, so I'm not yet sure where the best place to change things is, or whether some task is best done in a plugin or in changes to the main code. I would like to grab the mobi EXTH dcetype field -- specifically to identify Amazon Kindle samples from actual books. I also see that besides the three values documented on the wiki ( https://wiki.mobileread.com/wiki/MOBI ): cdetype: PDOC - Personal Doc; EBOK - ebook; EBSP - ebook sample; calibre uses another 'MAGZ' for magazines. ( This code may also be used by Amazon -- I see it in my NewYorker subscriptions, which I get from amazon, as well as others that I download from calibre.) My first step was just to stick in some lines in ebooks/mobi/reader/headers.py to print the value. I suppose that I could add a keyword like 'KindleSample' to the tags for that case, but it seems that this kind of classification info would be more generally useful. ( I've seen a thread in one of the other sub-forums asking how to identify Kindle samples, but without a clear answer. ) Since the dcetype code is specific to mobi format, I was wondering if there was a more generic field in the metadata that could hold this info. In ebooks/metadata/book/__init__.py I see: # So far only known publication type is periodical:calibre # If None, means book 'publication_type', I'm guessing that periodical:calibre maps into the 'MAGZ' code. Would this be a good place to add additional values to map PDOC & EBSP ? ( Other tips on how to understand and navigate the calibre code & classes is appreciated. I've been following the thread on custom columns, as I suppose the next part is figuring out how to make this value viewable and sortable. ) -- sdm |
