:: hark-store: notifications and unread counts [landscape]
::
:: hark-store can store unread counts differently, depending on the
:: resource.
:: - last seen. This way, hark-store simply stores an index into
:: graph-store, which represents the last "seen" item, useful for
:: high-volume applications which are intrinsically time-ordered. i.e.
:: chats, comments
:: - each. Hark-store will store an index for each item that is unread.
:: Usefull for non-linear, low-volume applications, i.e. blogs,
:: collections
::
