Opening a topic

Revision as of 19:59, 4 October 2006

In order to take a closer look at the topic you need to open it into a topic panel. There exists many different procedures to open a topic for detailed inspection in Wandora. For example:

• Clicking Open or Arrow button in button bar.
• Selecting Open topic from Topics menu or pressing Ctrl-O.
• Double clicking topic in topic tree or topic table.
• Selecting Open topic in context menu opened in topic tree.
• Selecting Open in context menu opened in topic table.

Some times it may be necessary to close topic open in topic panel. Topic is closed by selecting Close topic from Topics menu or pressing Ctrl-W.

Modifying basenames

Topic's basename is modified by changing the contents of basename text field in topic panel. Emptying field removes the basename. Wandora topic may have only one unscoped basename. Wandora application represents topics with basename by default and it is recommended that all topic's have basename.

Addition to direct topic panel editing basename can also be modified within topic tree triple clicking topic in tree. Operation changes topic's basename label into an editable basename field.

Topics->Basename menu contains more advanced basename editing options. Menu contains tool to remove new line characters in basename and tool to make basename outof subject identifier for example. Menu has four instances located within top menu bar, context menu of topic table and topic tree and within layer context menu. Each instance of Basename menu targets different set of topics and basenames.

Note: Basenames with new line characters are tricky because Wandora's basename field does not support the character. We strongly encourage you to use basename's without new line characters.

Modifying subject locators

Common method to modify subject locator is to open topic in topic panel and edit subject locators field. Emptying field removes subject locator. Wandora topic may contain only one subject locator.

Subject locator icon is shown at the top of topic panel. Subject locator icon depends on the type of subject locator file. If subject locator resolves image subject locator icon looks like the image. Right clicking the subject locator icon reveals context menu containing tools for the subject locator in question. For example context menu of image icon includes tools to resize icon image, copy image to clipboard, save image to local file etc.

Advanced subject locator tools locate in Topics->Subject locator menu. Advanced tools enable to check subject locator URL, download subject locator files and construction of subject locators for example. Menu has four instances of top menu bar, topic table, topic tree and layer stack. Each instance manages different set of topics and subject locators.

Modifying variant names

Variant names operate as language and scope dependent topic names. This is slightly different from topic map standard where variant names play modest role compared to basenames. Variant names are modified directly in topic panel's text fields.

For more advanced variant name operations use tools in Topics->Variant names menu. Similar to basename Wandora contains four different instances of this menu in top menu bar, topic table, topic tree and layer stack. Each instance manages different set of topics and subject locators.

By default Wandora supports four scopes (ie. languages) of Finnish, Swedish, English and Language Independent and two name types of Display name and Sort name. Extending the language and name type support is very easy. To add another language add new instance topic to Wandora language. To add another name type add new instance to topic Wandora variant name version. Both Wandora language and Wandora variant name version are instances of Schema type topic.

By default topic panel's variant name matrix has language paragraphs. Orientation of name matrix is changed to Flip name matrix tool found in context menu of Variant names title header.

Note: Although Wandora views only variant names of registered scopes and types other names remain under the surface of Wandora, in the topic map.

Add and delete subject identifiers

Subject identifier fields in topic panel contain Delete button. Subject identifier is removed by cllicking the button. If you remove topic's last subject identifier default subject identifier is created to the topic as soon as the topic is used next time. Wandora requires each existing topic has at least one valid subject identifier. To add subject identifier to a topic right-click at the Subject Identiers title of identifier table and select Add subject identifier.

Add and delete classes

Class topic describe type of the the topic. Class is added to a topic by right-clicking the title header Classes of class table and selecting Add class. Operation employs similar window as Open topic. Window is used to point the topic class. Class is deleted simply selecting row in class table, right-clicking the row and selecting Loose classes.... Multiple classes can be removed at once.

Add and delete instances

Instances and classes are symmetric. If A is a class of B then B is instance of A. Instance is added to a topic by right clicking the title header of Instances table and selecting Add instance.... Instance is deleted as classes by selecting row in instance table, right-clicking selected row and selecting Loose instances....

Add, modify and delete associations

Association is added by right clicking Associations header title and selecting Add schemaless association... or Add association.... Wandora employs simple schema to ease association creation and modification. Association schema defines what kind of associations are acceptable. Association schema is defined with topic map it self. Read more about the schema here. Till then you may add schemaless associations. Schemaless associations require you to pick up association's type, roles and players except the topic in question. Right-clicking the association row reveals powerful operations to modify association. You may for example change association's type and roles as well as delete the association.

Add, modify and delete text datas

Text datas are equivalent to occurrences of topic map standard. Text data is a solid text block describing or associating the topic. Wandora does not support URL occurrences of the topic map standard. Text data is added to a topic by right clicking the Text data header title and selecting Add text data.... Text datas employ similar schema as associations. Schema defines what kind of text datas can be added to a topic. Read more about the schema here.
