AngularJS topic map browser

The AngularJS Topic Map browser is a JTM based AngularJS app designed to provide a simple Topic Map browser for the user to navigate. The app loads a Topic Map presented in a simple JTM file and presents a simple UI built on Twitter Bootstap. Thus no instance of a JTM service is required for it's use.

Installation and running

The app is contained in the app subfolder, and is run by opening index.html in a browser. The app relies heavily on ajax requests which blocked by default in Chrome when opening pages from the filesystem. As a workaround the provided Node.js server should be run with node scripts/web-server.js.

The app is then accsessible in

localhost:8000/app/index.html

The project also supports building a stripped down distribution version of the app using Node.js and Grunt.

• The required dependencies are installed with npm install -g grunt-cli for a global installation of the Grunt command line interface

• npm install for the remaining dependencies.

• The compilation process is finally run with grunt dist which copies and compiles the required files to the build directory.

Configuration and customization

The main configuration and translation is stored in config.json

• dataUrl is used to specify the JTM file as a relative path.
• sis is used to specify special topics as type-instance and super-sub

associations and players. root is the root topic at the root of the subclass-superclass association tree.

• langs is used to specify the languages topics used in the app

• defaultLang is used to specify the default langauge

• translation is used to translate UI text elements to other languages.

A translation object should have the text literal written in the template files as one key-value-pair and it's translations as their respective key-value-pairs.

Further customization requires understaning of the Angular MVC framework.

Example

Run the server with node scripts/web-server.js from the app directory

Open localhost:8000/app/index.html to view the base topic specified in the config.json file.

• Browse the Art of Noise Bibliography topic by clicking on it. Note Angular's routing system remembering the topic si in the URL fragment making it possible to bookmark the page and browse the Topic Map with back and forward navigtion.
• Change the language from the menu at the top. Scopes available as languages in the browser are specified in config.json

• Browse the class and instance relations in the side bar. This is similar to the side bar in Wandora. Both relations and roles are also specified in config.json.
• Filter the track instances using the filter field provided by the app.

The build process

The app folder contains a version of the app suitable for development and testing.

It's usually useful to create a minified distribution package of the app for deployment purposes. The project folder includes a Gruntfile for producing this. We install the project dependecies for node as instructed in Installation and running

We can now server the project using the web-server.js script and visit the distribution app at localhost:8000/build/index.html
