Subject locator is an URL resource that is the topic. Topic may have zero or one subject locator. If two topics have same subject locator, topics merge automatically.
To modify topic's subject locator open the topic to a topic panel such as Traditional topic panel and edit panel's subject locator field. Writing URL to the field adds subject locator to the topic. Emptying the field removes topic's subject locator. Next image views Traditional topic panel and subject locator field marked with a red circle.
Although Wandora's topic map model does not resolve subject locators, Wandora application resolves the URL and views a thumbnail or an icon for the resource. Thumbnail or icon is viewed above the subject locator field in traditional topic panel. Some resource types such as image or HTML document can be modified with context tools. If subject locator resolves image, subject locator icon views the image. Right clicking the image icon reveals context menu with tools for the subject locator. For images the context menu contains tools to resize image, copy image, save image etc.
Advanced subject locator tools locate in Topics > Subject locator menu. Advanced tools enable the user to check subject locator URL, download subject locator files and construction of subject locators for example. More detailed:
- Open SL forks external application, Internet Explorer by default and passes the subject locator url to the application.
- Check SL resolves subject locator URL and reports whether or not the URL resolves to a real internet resource. This is useful when you have to check if subject locators of an old topic map are still valid.
- Download SL downloads the subject locator resource to local file system but doesn't change topic's subject locator.
- Move subject locator downloads the subject locator resource to local file system and changes subject locator to point this local copy of SL resource.
- Move to fileserver uploads the internet resource of subject locator URL to user specified file server and changes the subject locator to the address given by file server. File server refers here to a Wandora-Piccolo server.
- Extract with SL contains submenus, one for each Wandora extractor. Selecting extractor in this context applies the extractor to the subject locator resource.
- Regex replace changes topic's subject locator with user specified regular expression.
- Remove SL removes topic's subject locator.
- Make SL with base name construct subject locator for the topic using base name and user specified URL body.
- Make SL with occurrence constructs subject locator for the topic using occurrence data and user specified URL body.
These editing options may sound trivial if you consider modifying one subject locator. However, applying editing option to multiple topics at once is much more useful.
