+I have been messing around with calibre-web in a few different ways and thought I would share them. I am currently working on a couple of features: -
 
 1. Marking books as read/unread. In the Book View, there is now a row that says whether or not a book is read. If you click it, it will toggle. Further down the line, I plan on adding goodreads support, which if the book has a goodreads link, it will automatically move the book to the "to read" and "read" bookshelves.
 
-2. Google drive support. In my local version, I currently have this working, but it is essentially to make the website have all the books / covers / metadata.db served directly from google drive. I am currently, still optimising a bit of code, and will hopefully have this on GitHub ASAP.

-# What is the PDFX namespace, you might ask?  I might ask that too.  It's
-# a completely undocumented namespace used to place "custom metadata"
-# properties, which are arbitrary metadata properties with no semantic or
-# documented meaning.  Elements in the namespace are key/value-style storage,
-# where the element name is the key and the content is the value.  The keys
-# are transformed into valid XML identifiers by substituting an invalid
-# identifier character with \u2182 followed by the unicode hex ID of the
-# original character.  A key like "my car" is therefore "my\u21820020car".
-#
-# \u2182, in case you're wondering, is the unicode character
-# \u{ROMAN NUMERAL TEN THOUSAND}, a straightforward and obvious choice for
-# escaping characters.
-#
-# Intentional users of the pdfx namespace should be shot on sight.  A
-# custom data schema and sensical XML elements could be used instead, as is
-# suggested by Adobe's own documentation on XMP (under "Extensibility of
-# Schemas").
-#
-# Information presented here on the /pdfx/ schema is a result of limited
-# reverse engineering, and does not constitute a full specification.

-    By default, some web browsers unfortunately do not include the territory

-    the language-only locale sent by such browsers. To workaround that, this

-    identifiers to identifiers including the territory:
-
-    >>> negotiate_locale(['ja', 'en_US'], ['ja_JP', 'en_US'])

-    Some browsers even use an incorrect or outdated language code, such as "no"
-    for Norwegian, where the correct locale identifier would actually be "nb_NO"
-    (Bokmål) or "nn_NO" (Nynorsk). The aliases are intended to take care of
-    such cases, too:
-
-    >>> negotiate_locale(['no', 'sv'], ['nb_NO', 'sv_SE'])

-
