Tagging Branches

Menu Option: Tree: Tags

In addition to organizing your analysis using LEAP's tree structure (e.g., organizing a demand analysis into sectors, sub-sectors, end-uses and technologies) you can also use tags () to help organize your data.  While the hierarchy of LEAP's tree structure is most useful for organizing data  that can clearly be assigned to single categories (folders), tags can be helpful for classifying technologies that belong to more than one category.  

Consider the example of an electric generation Transformation module.  You may decide to create a very long list of processes () to represent the various types of electric generation technologies that currently exist or that may perhaps be built in the future.  Some of these technologies may represent specific individual power plants, while others may represent generic types of power plants.  These technologies need to be entered in LEAP as a single long list (since LEAP's Transformation branches do not allow for creating sub folders).  Without tags, viewing the results for Electric Generation would be a challenge since you would have to view results for each individual process.

This is where tags come in. You can assign one or more tags to each branch and then use these tags to filter and organize your results.  In the example above, you might chose to tag your power plants according to whether they were thermal, renewable or nuclear technologies, or whether they were existing, or new types of power plants.  You might also choose to tag them depending on whether they were specific power plants in the area being studied or whether they were generic types of technologies (for example, by assigning the tags "specific" and "generic").  You may even choose to tag the power plants based on their technology (for example, Combustion Turbine, Combined Cycle, IGCC, CCS, etc.)  Thus, tags give you a lot of flexibility in how to categorize branches.  When using tags for viewing results, each branch must only be tagged with a single tag from any one tag group.  Once you have created tags at different branches, you can use Tags as an additional selectable dimension in your Results View charts and tables.  


To create tags in LEAP, use the tag toolbar in Analysis View (shown above).  You can simply type in a set of labels to represent each of your tags separated by commas.  Alternatively you can add an existing tag using the Add button, or delete a tag using the Delete button. You can organize your tags into color coded groups using the Manage Tags screen (Alt+T).  Use the Tag Painter button () to "paint" tags by first selecting a branch containing the tags you want to paint, and then selecting one or more of those tags to "paint" onto other branches.  When in tag painting mode, hover over a branch to see its name and what tags it currently has.  Press Escape or click outside of the tree to exit Tag painting mode.  Use the Color button () to display the Tree using the colors associated with particular Tag Groups.  If you don't want to color code the tree, select "None".  Use the Tag Settings options to select how tags are applied.  Use the Add To Existing Tags option to select if tags are added to the set of tags already associated with a branch, or if the tags replace the existing tags at a branch.  Use the Tag Children option to select if tags are applied to the current branch and all children below it or to the current branch alone.  This option affects both adding and deleting of branches.  Finally, a Delete All option () allows you to delete all tags at all branches.
