< p class = "inwebparagraph" > < a id = "SP1" > < / a > < b > § 1. Works. < / b > A "work" is a single artistic or programming creation; for example, the IF
story Bronze by Emily Short might be a work. Mamy versions of this IF story
may exist over time, but they will all be versions of the same "work".
Extensions are also works: for example, Epistemology by Eric Eve is a work.
< / p >
< p class = "inwebparagraph" > Works are identified by the pair of title and author name, each of which is an
ISO Latin-1 string limited in length, with certain bad-news characters
excluded (such as < code class = "display" > < span class = "extract" > /< / span > < / code > and < code class = "display" > < span class = "extract" > :< / span > < / code > ) so that they can be used directly in filenames.
However, we will not want to compare these by string comparison: so we
hash-code the combination for speed. The following structure holds a
combination of the textual names and the hash code:

already of normalised casing, we do not want to rely on that. Works intending
to represent (e.g.) the same extension but named with different casing
conventions would fail to match: and this could happen if a new build of
Inform were published which made a subtle change to the casing conventions,
but which continued to use an extension dictionary file first written by
previous builds under the previous conventions.

an installed extension with this work?" and "does any entry in the dictionary
relate to this work?": there may be many extensions and very many dictionary
entries, so we keep an incidence count of each work and in what context it
has been used, and store that in a hash table. Note that each distinct work
is recorded only once in the table: this is important, as although an
individual extension can only be loaded or installed once, it could be
referred to in the dictionary dozens or even hundreds of times.
