==== Ruby Topic Maps (RTM) RTM is a Topic Maps engine written in Ruby. See http://rtm.topicmapslab.de/ for instructions. Several backends and extensions are available as separate gems. ==== Overview From a developer's perspective, RTM is a schema-less database management system. The Topic Maps standard (described below) on which RTM is based provides a way of creating a self-describing schema just by using it. ==== Quickstart require 'rtm' connection = RTM.connect # uses the default Ontopia in-memory backend topic_map = connection.create "http://example.org/my_topic_map/" some_topic = topicmap.get!("identifier_of_the_topic") some_topic["-"] = "default name for the topic" topic_map.to_xtm("my_xtm_file.xtm") ==== Topic Maps Topic Maps is an international industry standard (ISO13250) for interchangeably representing information about the structure of information resources used to define topics, and the relationships between topics. A set of one or more interrelated documents that employs the notation defined by this International Standard is called a topic map. A topic map defines a multidimensional topic space - a space in which the locations are topics, and in which the distances between topics are measurable in terms of the number of intervening topics which must be visited in order to get from one topic to another, and the kinds of relationships that define the path from one topic to another, if any, through the intervening topics, if any. In addition, information objects can have properties, as well as values for those properties, assigned to them. The Topic Maps Data Model which is used in this implementation can be found on http://www.isotopicmaps.org/sam/sam-model/. ==== Backends * rtm-ontopia: JRuby only, recommended, uses Ontopia: http://code.google.com/p/ontopia/ * rtm-tinytim: JRuby only, uses TinyTiM: http://tinytim.sourceforge.net/ * rtm-activerecord: uses a custom ActiveRecord schema ==== Extensions * rtm-tmql: Adds support for the Topic Maps Query Language (TMQL), http://isotopicmaps.org/tmql/ * rtm-tmcl: Adds support for the Topic Maps Constraint Language (TMCL), http://isotopicmaps.org/tmcl/ ==== License Copyright 2009 Topic Maps Lab, University of Leipzig.

==== Topic Maps for Rails (rtm-rails) RTM-Rails is the Rails-Adapter for Ruby Topic Maps. It allows simple configuration of topicmaps in config/topicmaps.yml. ==== Overview From a developer's perspective, RTM is a schema-less database management system. The Topic Maps standard (described below) on which RTM is based provides a way of creating a self-describing schema just by using it. You can use RTM as a complement data storage to ActiveRecord in your Rails apps. ==== Quickstart - existing Rails project jruby script/generate topicmaps Run the command above after installing rtm-rails. This will create * a minimal default configuration: config/topicmaps.yml and * a file with more examples and explanations config/topicmaps.example.yml * a file README.topicmaps.txt which contains more information how to use it and where to find more information * an initializer to load the topicmaps at startup * a rake task to migrate the topic maps backends in your rails application. ==== Quickstart - new Rails project For a new Rails application these are the complete initial steps: jruby -S rails my_topicmaps_app cd my_topicmaps_app jruby -S script/generate jdbc jruby -S script/generate topicmaps # The following lines are necessary because Rails does not have a template # for the H2 database and Ontopia does not support the Rails default SQLite3. sed -e "s/sqlite3/h2/" config/database.yml > config/database.yml.h2 mv config/database.yml.h2 config/database.yml # Prepare the database and then check if all is OK jruby -S rake topicmaps:migrate_backends jruby -S rake topicmaps:check ==== Usage inside the application When everything is fine, let's create our first topic: jruby -S script/console TM[:example].get!("http://example.org/my/first/topic") # and save the topic map TM[:example].commit Access the configured topic maps anywhere in your application like this: TM[:example] To retrieve all topics, you can do TM[:example].topics To retrieve a specific topic by its subject identifier: TM[:example].get("http://example.org/my/topic") Commit the changes to the database permanently: TM[:example].commit ... or abort the transaction: TM[:example].abort More information can be found on http://rtm.topicmapslab.de/ ==== Minimal configuration default: topicmaps: example: http://rtm.topicmapslab.de/example1/ The minimal configuration creates a single topic map, named :example with the locator given. This topic map will be persisted in the same database as your ActiveRecord connection if not specified otherwise. The default backend is OntopiaRDBMS (from the rtm-ontopia gem). A more complete configuration can be found in config/topicmaps.example.yml after running "jruby script/generate topicmaps". It also includes how to specifiy multiple connections to different data stores and so on. ==== Topic Maps Topic Maps is an international industry standard (ISO13250) for interchangeably representing information about the structure of information resources used to define topics, and the relationships between topics.

U U extends Ruby’s Unicode support. It provides a string class called U::String with an interface that mimics that of the String class in Ruby 2.0, but that can also be used from both Ruby 1.8. This interface also has more complete Unicode support and never modifies the receiver. Thus, a U::String is an immutable value object. U comes with complete and very accurate documentation¹. The documentation can realistically also be used as a reference to the Ruby String API and may actually be preferable, as it’s a lot more explicit and complete than the documentation that comes with Ruby. ¹ See http://disu.se/software/u-1.0/api/ § Installation Install u with % gem install u § Usage Usage is basically the following: require 'u-1.0' a = 'äbc' a.upcase # ⇒ 'äBC' a.u.upcase # ⇒ 'ÄBC' That is, you require the library, then you invoke #u on a String. This’ll give you a U::String that has much better Unicode support than a normal String. It’s important to note that U only uses UTF-8, which means that #u will try to #encode the String as such. This shouldn’t be an issue in most cases, as UTF-8 is now more or less the universal encoding – and rightfully so. As U::Strings¹ are immutable value objects, there’s also a U::Buffer² available for building U::Strings efficiently. See the API³ for more complete usage information. The following sections will only cover the extensions and differences that U::String exhibit from Ruby’s built-in String class. ¹ See http://disu.se/software/u-1.0/api/U/String/ ² See http://disu.se/software/u-1.0/api/U/Buffer/ ³ See http://disu.se/software/u-1.0/api/ § Unicode Properties There are quite a few property-checking interrogators that let you check if all characters in a U::String have the given Unicode property: • #alnum?¹ • #alpha?² • #assigned?³ • #case_ignorable?⁴ • #cased?⁵ • #cntrl?⁶ • #defined?⁷ • #digit?⁸ • #graph?⁹ • #newline?¹⁰ • #print?¹¹ • #punct?¹² • #soft_dotted?¹³ • #space?¹⁴ • #title?¹⁵ • #valid?¹⁶ • #wide?¹⁷ • #wide_cjk?¹⁸ • #xdigit?¹⁹ • #zero_width?²⁰ ¹ See http://disu.se/software/u-1.0/api/U/String/#alnum-p-instance-method ² See

http://disu.se/software/u-1.0/api/U/String/#zero_width-p-instance-method Similar to these methods are • #folded?¹ • #lower?² • #upper?³ which check whether a ‹U::String› has been cased in a given manner. ¹ See http://disu.se/software/u-1.0/api/U/String/#folded-p-instance-method ² See http://disu.se/software/u-1.0/api/U/String/#lower-p-instance-method ³ See http://disu.se/software/u-1.0/api/U/String/#upper-p-instance-method There’s also a #normalized?¹ method that checks whether a ‹U::String› has been normalized on a given form. ¹ See http://disu.se/software/u-1.0/api/U/String/#normalized-p-instance-method You can also access certain Unicode properties of the characters of a U::String: • #canonical_combining_class¹ • #general_category² • #grapheme_break³ • #line_break⁴ • #script⁵ • #word_break⁶ ¹ See http://disu.se/software/u-1.0/api/U/String/#canonical_combining_class-instance-method ² See

http://disu.se/software/u-1.0/api/U/String/#word_break-instance-method § Locale-specific Comparisons Comparisons of U::Strings respect the current locale (and also allow you to specify a locale to use): ‹#<=>›¹, #casecmp², and #collation_key³. ¹ See http://disu.se/software/u-1.0/api/U/String/#comparison-operator ² See http://disu.se/software/u-1.0/api/U/String/#casecmp-instance-method ³ See http://disu.se/software/u-1.0/api/U/String/#collation_key-instance-method § Additional Enumerators There are a couple of additional enumerators in #each_grapheme_cluster¹ and #each_word² (along with aliases #grapheme_clusters³ and #words⁴). ¹ See http://disu.se/software/u-1.0/api/U/String/#each_grapheme_cluster-instance-method ² See http://disu.se/software/u-1.0/api/U/String/#each_word-instance-method ³ See http://disu.se/software/u-1.0/api/U/String/#grapheme_clusters-instance-method ⁴ See http://disu.se/software/u-1.0/api/U/String/#words-instance-method § Unicode-aware Sub-sequence Removal #Chomp¹, #chop², #lstrip³, #rstrip⁴, and #strip⁵ all look for Unicode newline and space characters, rather than only ASCII ones. ¹ See http://disu.se/software/u-1.0/api/U/String/#chomp-instance-method ² See http://disu.se/software/u-1.0/api/U/String/#chop-instance-method ³ See

http://disu.se/software/u-1.0/api/U/String/#strip-instance-method § Unicode-aware Conversions Case-shifting methods #downcase¹ and #upcase² do proper Unicode casing and the interface is further augmented by #foldcase³ and #titlecase⁴. #Mirror⁵ and #normalize⁶ do conversions similar in nature to the case-shifting methods. ¹ See http://disu.se/software/u-1.0/api/U/String/#downcase-instance-method ² See http://disu.se/software/u-1.0/api/U/String/#upcase-instance-method ³ See

http://disu.se/software/u-1.0/api/U/String/#mirror-instance-method ⁶ See http://disu.se/software/u-1.0/api/U/String/#normalize-instance-method § Width Calculations #Width¹ will return the number of cells on a terminal that a U::String will occupy. #Center², #ljust³, and #rjust⁴ deal in width rather than length, making them much more useful for generating terminal output. #%⁵ (and its alias #format⁶) similarly deal in width. ¹ See http://disu.se/software/u-1.0/api/U/String/#width-instance-method ² See http://disu.se/software/u-1.0/api/U/String/#center-instance-method ³ See
