* Clicking '''Open''' button in button bar. This opens a topic selection dialog where you can browse and search topics, and select the topic you wish to open.
* Selecting '''Open topic''' from Topics menu or pressing ''Ctrl-O''.
+
* Clicking '''Arrow''' button in button bar. Arrows are used to navigate the browse history. Left arrow restores previous topic. Right arrow restores next topic in browse history.
* Double clicking topic in topic tree or topic table.
+
* Selecting '''Open topic''' from Topics menu or pressing ''Ctrl-O''. '''Open topic''' menu option is available in several locations in Wandora.
* Selecting '''Open topic''' in context menu opened in topic tree.
+
* Double clicking a topic in [[Working with topic trees|topic tree]] or [[Working with topic tables|topic table]]. This is easiest method to open a topic. If you can see the topic in any topic tree or topic table, just double click it and it is opened to the topic panel.
* Selecting '''Open''' in context menu opened in topic table.

==Modifying base names==
+
* [[Topic shortcuts]]
 
+
Topic's base name is modified by changing the contents of base name text field in topic panel. Emptying field removes the base name. Topic may have only one unscoped base name in Wandora. By default Wandora uses base name as a topic representation. It is recommended all topics have base name. We strongly encourage you not to use new line characters in base name's as Wandora's base name field does not support the character.
+
 
+
Addition to topic panel editing, base name can also be modified within a topic tree. Clicking the topic three times in the tree changes topic's base name label into an editable base name field.
+
 
+
'''Topics > Base name''' menu contains more advanced base name editing options. These advanced editing options include
+
 
+
* '''Regex replace''' allows you to modify base name with regular expressions.
+
* '''Remove new line characters''' simply removes all new line characters in topic's base name.
+
* '''Remove base name''' removes topic's base name.
+
* '''Make base name with SI''' 
+
* '''Make base name with text data'''
+
 
+
==Modifying subject locators==
+
 
+
Common method to modify subject locator is to a open topic to topic panel and edit subject locator field. Emptying the field removes topic's subject locator. Topic may contain only one subject locator in Wandora.
+
 
+
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 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.
+
 
+
==Modifying variant names==
+
 
+
Variant names operate as language and scope dependent topic names. This is slightly different from the topic map standard where variant names play modest role compared to base names. Variant names are modified directly in topic panel.
+
 
+
For more advanced variant name operations use tools in '''Topics > Variant names'''.
+
 
+
By default Wandora supports four scopes (ie. languages) of Finnish, Swedish, English, and Language Independent. By default Wandora also supports two name types of Display name and Sort name. Extending the language and the name type support is very easy. To add another language add new instance topic to '''Wandora language''' topic. 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. Although Wandora views only variant names of registered scopes and types, other names remain intact in the topic map.
+
 
+
By default topic panel's variant name matrix has language paragraphs. Orientation of name matrix is changed with '''Flip name matrix''' tool found in context menu of Variant names title header.
+
 
+
Variant names should not contain new line characters because Wandora's variant name field contain single row.
+
 
+
==Modifying subject identifiers==
+
 
+
Topic panel doesn't allow direct edition of subject identifiers. To change subject indentifier you need to add new subject identifier to the topic and then remove the old one. This rather illogical order of actions is required because topic must always hold at least one subject identifier. If you remove topic's last subject identifier a default subject identifier is added to the topic.
+
 
+
 
+
[[Image:Add_si.gif|center|Subject identifier is added to a topic with external dialog]]
+
 
+
 
+
Subject identifier is removed by clicking '''Delete''' button beside the identifier. Subject identifier is added to a topic by selecting '''Add subject identifier''' in context menu of the Subject Identiers title header.
+
 
+
More advanced tools to modify subject identifiers is found in '''Topics > Subject identifiers''' menu.
+
 
+
==Modifying topic classes==
+
 
+
Class is a topic that describes the type of the topic. Each topic may contain zero or more classes.
+
 
+
Class is added to a topic by right-clicking the title header '''Classes''' and selecting '''Add class'''. Operation employs pick-a-topic-type window used to point the topic class. Topic's class is deleted selecting a row in the class table, right-clicking the row and selecting '''Loose classes...'''. Multiple classes can be removed at once.
+
 
+
Also '''Topics > Add to topic > Add class''' menu selection adds topic a class and '''Topics > Delete from topic > Loose classes''' deletes the class but leaves the class topic intact.
+
 
+
==Modifying topic instances==
+
 
+
Instance is added to a topic by right clicking the title header of Instances table and selecting '''Add instance...'''. Instance is deleted by selecting row in the instance table, right-clicking selected row and selecting '''Loose instances...'''.
+
 
+
Also menu selections '''Topics > Add to topic > Add instance''' and '''Topics >Delete from topic > Loose instances''' can be used to add and delete instances.
+
 
+
==Modifying associations==
+
 
+
Associations are perhaps the most important feature of topics. Associations links topics together into doubles, triplets etc.
+
 
+
Association is added to a topic by selecting '''Add schemaless association...''' or '''Add association...''' in context menu of Associations header. Wandora employs simple schema to ease association creation and modification. Association schema defines what kind of associations are acceptable, ie. types, roles and players of allowed associations. Association schema is defined with instances and subclasses of '''Schema type''' topic. Guidelines to build a modest schema are outside the scope of this text. Read more about the schema [[Schema|here]].
+
 
+
 
+
[[Image:association_editor.gif|center|Adding association to a topic with schema]]
+
 
+
 
+
Building a working schema for associations may be extravagant for small or ad hoc projects. Schemaless associations give you a moderate convention to add and modify associations without explisit schema definitions. Schemaless associations force you to pick separately association's roles, players and type.
+
 
+
 
+
[[Image:schemaless_association_editor.gif|center|Adding association to a topic without schema]]
+
 
+
 
+
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.
+
 
+
==Modifying occurrences==
+
 
+
Occurrence is a solid text block associated to the topic. Wandora does not support URL occurrences of the topic map standard. However, it is possible to set URL's external representation, the string representing URL, as the occurrence.
+
 
+
 
+
[[Image:textdata_editor.gif|center|Adding occurrence to a topic with predefined schema.]]
+
 
+
 
+
 
+
Occurrence is added to a topic by selecting '''Add schemaless text data...''' or '''Add text data...'''. Occurrences employ similar schema as associations. Occurrence schema defines what kind of occurrences can be added to a topic i.e. the types of allowed occurrences. Read more about the schema [[Schema|here]]. As schema creation is rather difficult schemaless occurrence addition is also allowed.
+
 
+
More advanced occurrence operations are found in '''Topics > occurrence''' menu of topic tables.

In order to take a closer look at any topic you need to open it into a topic panel, traditional topic panel for example. There are many different procedures to open a topic for inspection. These procedures include:

  • Clicking Open button in button bar. This opens a topic selection dialog where you can browse and search topics, and select the topic you wish to open.
  • Clicking Arrow button in button bar. Arrows are used to navigate the browse history. Left arrow restores previous topic. Right arrow restores next topic in browse history.
  • Selecting Open topic from Topics menu or pressing Ctrl-O. Open topic menu option is available in several locations in Wandora.
  • Double clicking a topic in topic tree or topic table. This is easiest method to open a topic. If you can see the topic in any topic tree or topic table, just double click it and it is opened to the topic panel.
  • Selecting Open topic in context menu opened in topic tree.
  • Selecting Open in context menu opened in topic tables.

Once topic has been opened in topic panel, it can be examined and modified (if the topic panel supports topic editing). Sometimes it may be necessary to close the topic in the topic panel. A topic is closed by selecting Close topic from Topics menu or pressing Ctrl-W.
