Breadcrumb list supplementing for hierarchical data sets
A breadcrumb path for use in navigating a hierarchical data set may be supplemented with one or more supplemental breadcrumbs representing preferred locations within the hierarchical data set. The supplemental breadcrumb may represent a previously visited location within the hierarchical data set, and may be further limited to the previously visited locations that are subordinate to the currently selected location. The supplemental breadcrumb may also represent a frequently visited location within the hierarchical data set. For scoped hierarchical data sets, the preferred location may represent a previously visited location within the scope of the selected location, or a frequently visited location within the scope of the selected location. Several embodiments of user interface components featuring such supplemented breadcrumb lists and having various advantages are presented, as well as a few contexts for applying such supplemental breadcrumbs in a breadcrumb list.
1. A method of facilitating navigation in a hierarchical data set, the method comprising:
generating a breadcrumb list representing a path from a root node to a selected node in the hierarchical data set;
adding to the breadcrumb list at least one supplemental breadcrumb representing a preferred location in the hierarchical data set, the preferred location selected from a preferred location set comprising:
at least one node of the hierarchical data set that is conceptually related to the selected node; and
at least one node of the hierarchical data set having a relationship with at least one user; and
displaying the breadcrumb list.
2. The method of claim 1 , the preferred location of at least one node of hierarchical data set having a relationship with at least one user comprising: a node of the hierarchical data set representing a previously visited location that has been previously visited by a user.
3. The method of claim 2 , the previously visited location comprising a previously visited location within the hierarchical data set that is subordinate to the selected node.
4. The method of claim 3 ,
respective nodes of the hierarchical data set configured to record in a subordinate node visit memory the visited subordinate nodes of the selected node, and
the breadcrumb list comprising supplemental breadcrumbs representing the visited subordinate nodes represented in the subordinate node visit memory of the selected node.
5. The method of claim 2 :
the hierarchical data set comprising a scoped hierarchical data set; and
the previously visited location comprising a previously visited location within the hierarchical scope of the selected node.
6. The method of claim 1 , the preferred location comprising a frequently visited location within the hierarchical data set.
7. The method of claim 6 , the hierarchical data set comprising a scoped hierarchical data set, the frequently visited location comprising a frequently visited location that shares the hierarchical scope of the selected node.
8. The method of claim 1 , the displaying comprising displaying a supplemental breadcrumb indicator configured to toggle displaying the at least one supplemental breadcrumb.
9. The method of claim 1 , the displaying comprising displaying a supplemental breadcrumb indicator configured to toggle displaying the at least one supplemental breadcrumb.
10. The method of claim 1 :
the selected node selected by a user; and
the at least one node of the hierarchical data set that has been previously visited by a user comprising: at least one node of the hierarchical data set that has been previously visited by the user selecting the selected node.
11. The method of claim 1 , displaying the breadcrumb list comprising:
displaying the breadcrumb list as a one-dimensional list of breadcrumbs including the at least one supplemental breadcrumb.
12. A computer-readable storage medium storing processor-executable instructions configured to facilitate navigation in a hierarchical data set by:
generating a breadcrumb list representing a path from a root node to a selected node in the hierarchical data set;
adding to the breadcrumb list at least one supplemental breadcrumb representing a preferred location in the hierarchical data set, the preferred location selected from a preferred location set comprising:
at least one node that is conceptually related to the selected node; and
at least one node having a relationship with at least one user; and displaying the breadcrumb list.
13. A method of facilitating navigation in a hierarchical data set, the method comprising:
generating a breadcrumb list representing a path from a root node to a selected node in the hierarchical data set;
appending to the breadcrumb list at least one supplemental breadcrumb representing a preferred location in the hierarchical data set; and
displaying the breadcrumb list as a one-dimensional sequence of breadcrumbs appending the at least one supplemental breadcrumb.
14. The method of claim 13 , the one-dimensional list of breadcrumbs comprising a horizontally ordered series of breadcrumbs.
15. The method of claim 13 , at least one preferred location represented by at least one supplemental breadcrumb comprising a location of at least one node of the hierarchical data set that is conceptually related to the selected node.
16. The method of claim 13 , the preferred location of at least one node of the hierarchical data set having a relationship with at least one user comprising: a node of the hierarchical data set representing a previously visited location that has previously visited by a user.
17. The method of claim 13 , at least one preferred location represented by at least one supplemental breadcrumb comprising a location of at least one node of the hierarchical data set having a relationship with at least one user.
18. The method of claim 13 , at least one breadcrumb of the breadcrumb list representing at least two nodes of the hierarchical data set.
19. A computer-readable storage medium storing processor-executable instructions configured to facilitate navigation in a hierarchical data set by:
generating a breadcrumb list representing a path from a root node to a selected node in the hierarchical data set;
appending to the breadcrumb list at least one supplemental breadcrumb representing a preferred location in the hierarchical data set; and
displaying the breadcrumb list as a one-dimensional sequence of breadcrumbs appending the at least one supplemental breadcrumb.
