Revisit links and pages

[bryanrcarlson]

We need a deep philosophical/metaphysical/existential discussion on pages, links, and nav.

Midden used to be just datasets but now there are tags, projects, zones, etc. It makes some sense to list these elements but this complicates navigation.

In the 0.2-dev.2 build there are catalog pages for the above elements. But things get weird fast. For example:

catalog/dataset lists all datasets for all zones. catalog/zones lists all the data zones. If you follow a zone link it goes to catalog/zones/{specific-zone} that lists all the datasets in that zone. But shouldn't this be the dataset catalog, just filtered by zone? Something like: catalog/datasets/zones/{specific-zone}? But if we have that, then what does catalog/datasets/zones list? All data for all zones? That's the same as catalog/datasets!

Simple solution: nuke the breadcrumbs, leave the REST-friendly URLs but don't link to them, shift to a catalog focus URL scheme (catalog/projects, catalog/datasets, catalog/datasets/zones/{zone}/projects/{project}).
