  • Assessment of Options for Handling Full Unicode Character Encodings in MARC21 a Study for the Library of Congress
    1 Assessment of Options for Handling Full Unicode Character Encodings in MARC21 A Study for the Library of Congress Part 1: New Scripts Jack Cain Senior Consultant Trylus Computing, Toronto 1 Purpose This assessment intends to study the issues and make recommendations on the possible expansion of the character set repertoire for bibliographic records in MARC21 format. 1.1 “Encoding Scheme” vs. “Repertoire” An encoding scheme contains codes by which characters are represented in computer memory. These codes are organized according to a certain methodology called an encoding scheme. The list of all characters so encoded is referred to as the “repertoire” of characters in the given encoding schemes. For example, ASCII is one encoding scheme, perhaps the one best known to the average non-technical person in North America. “A”, “B”, & “C” are three characters in the repertoire of this encoding scheme. These three characters are assigned encodings 41, 42 & 43 in ASCII (expressed here in hexadecimal). 1.2 MARC8 "MARC8" is the term commonly used to refer both to the encoding scheme and its repertoire as used in MARC records up to 1998. The ‘8’ refers to the fact that, unlike Unicode which is a multi-byte per character code set, the MARC8 encoding scheme is principally made up of multiple one byte tables in which each character is encoded using a single 8 bit byte. (It also includes the EACC set which actually uses fixed length 3 bytes per character.) (For details on MARC8 and its specifications see: http://www.loc.gov/marc/.) MARC8 was introduced around 1968 and was initially limited to essentially Latin script only.

  • The Braillemathcodes Repository
    Proceedings of the 4th International Workshop on "Digitization and E-Inclusion in Mathematics and Science 2021" DEIMS2021, February 18–19, 2021, Tokyo _________________________________________________________________________________________ The BrailleMathCodes Repository Paraskevi Riga1, Theodora Antonakopoulou1, David Kouvaras1, Serafim Lentas1, and Georgios Kouroupetroglou1 1National and Kapodistrian University of Athens, Greece Speech and Accessibility Laboratory, Department of Informatics and Telecommunications [email protected], [email protected], [email protected], [email protected], [email protected] Abstract Math notation for the sighted is a global language, but this is not the case with braille math, as different codes are in use worldwide. In this work, we present the design and development of a math braille-codes' repository named BrailleMathCodes. It aims to constitute a knowledge base as well as a search engine for both students who need to find a specific symbol code and the editors who produce accessible STEM educational content or, in general, the learner of math braille notation. After compiling a set of mathematical braille codes used worldwide in a database, we assigned the corresponding Unicode representation, when applicable, matched each math braille code with its LaTeX equivalent, and forwarded with Presentation MathML. Every math symbol is accompanied with a characteristic example in MathML and Nemeth. The BrailleMathCodes repository was designed following the Web Content Accessibility Guidelines. Users or learners of any code, both sighted and blind, can search for a term and read how it is rendered in various codes. The repository was implemented as a dynamic e-commerce website using Joomla! and VirtueMart. 1 Introduction Braille constitutes a tactile writing system used by people who are visually impaired.

  • What Is Braille
    Search Braille was first developed about 1820 by a young Frenchman named Louis Braille. He created Braille by modifying a system of night writing which was intended for use on board ships. He did this work as a very young man and had it complete by the time he was about 18. He and his friends at the school for the blind he attended found that reading and writing dots was much faster than reading raised print letters which could not be written by hand at all. The development of this system by young Louis Braille is now recognized as the most important single development in making it possible for the blind to get a good education. It took more than a century, however, before people would accept Braille as an excellent way for the blind to read and write. Even today many people underestimate the effectiveness of Braille. While tapes and records are enjoyable, Braille is essential for note taking and helpful for studying such things as math, spelling, and foreign languages. Experienced Braille readers, however, read Braille at speeds comparable to print readers--200 to 400 words a minute. Such Braille readers say that the only limitation of Braille is that there isn't enough material available. Braille consists of arrangements of dots which make up letters of the alphabet, numbers and punctuation marks. The basic Braille symbol is called the Braille cell and consists of six dots arranged in the formation of a rectangle, three dots high and two across. Other symbols consist of only some of these six dots.
