Abstract:
For concreteness, because the universal character set is not yet
universal, and because an international standard for the internet
community should be documented and stable, this I-D has been released
with the intention of producing an RFC to document the character use
and naming conventions of the SignWriting community on the Internet.
The SignWriting Script is an international standard for writing sign
languages by hand or with computers. From education to research,
from entertainment to religion, SignWriting has proven useful because
people are using it to write signed languages. The SignWriting
Script has two major families: Block Printing for the reader and
Handwriting for the writer.
Formal SignWriting uses ASCII strings to name logographic signs. The
mathematical names are explained with tokens and regular expression
patterns. Symbol keys reference the symbols of the International
SignWriting Alphabet 2010. Coordinates define X and Y number values
for 2-dimensional placement. Signs are written in a spatial SignBox,
where each symbol is positioned with a 2-dimension coordinate. For
sorting, each sign can have an optional temporal sequence of symbols
that is outside of the SignBox and the visible text. To create
sentences, completed signs are written sequentially, interspersed
with punctuation symbols.
The query language of Formal SignWriting uses a lite markup, similar
to FSW, to define a variety of searching possibilities. The spatial
SignBox can be searched for symbols or ranges of symbols. For each
symbol or range, the search can specify if the symbol only needs to
be found somewhere in the SignBox, or if the symbol needs to be found
near certain coordinates. The temporal sequence can be searched for
starting symbols, written as a sequential list of symbols and ranges
of symbols. When searching the temporal sequence, the search results
will be limited to signs that start with a matching temporal
sequence. Each query string is transformed into one or more regular
expressions. The regular expressions are used to quickly search
large amounts of data.
The styling string of Formal SignWriting uses a lite markup to define
a variety of styling options. The entire sign can be customized for
padding, coloring, and size. Individual symbols within a sign can be
customized for coloring and size.
SignWriting 2010 is the modern implementation and international
specification of the SignWriting Script for the internet community
that includes TrueType Fonts and a compact JavaScript library.
SignMaker is a standards based editor, utilizing HTML, CSS,
JavaScript, SVG, TrueType Fonts, and PNG images. SignMaker can be
used to create a private dictionary or to view dozens of sign
language dictionaries derived from SignPuddle Online.
For Unicode, there are several encodings possibilities. Formal
SignWriting is UTF-8. The plane 15 encoding is isomorphic with
Formal SignWriting strings, using 3 characters for each symbol, along
with structural marker characters and number characters. The plane
16 encoding is focused on the symbols only, using 1 character for
each symbol. The Unicode 8 specification uses 1 to 3 characters on
plane 1 to name each symbol of the International SignWriting Alphabet
2010.
Three appendices discuss additional topics to the standard. The
first discusses the Modern SignWriting theory and example document,
stable since January 12, 2012. The second discusses the symbol
encoding of the International SignWriting Alphabet 2010. The third
discusses the SignPuddle Standards: licences, infrastructure, and
compatibility.
This memo concretely defines a conceptual character encoding map for
the Internet community. It is published for reference, examination,
implementation, and evaluation. Distribution of this memo is
unlimited.
