+1. Each mathematical object should have its own home page.  Home pages
+summarize basic invariants at the top, progressing to more advanced
+information at the bottom, with mathematical terms defined by knowls.
+The right hand side of each home page should include a properties box
+that summarizes key invariants, links to completeness, source, and
+reliability knowls, and when applicable, a list of related objects.
+2. Each home page should have a mathematically meaningful, permanent URL.
+3. Each mathematical object should be given a label that is mathematically
+meaningful, and to the extent possible, human-readable and concise.
+The translation between an object's label and its URL should be
+relatively straightforward.
+4. Each home page should list the names of the entities responsible
+for producing the data on that page.
+5. Each class of objects has a browse-and-search page, which has
+browsing options in the upper portion of the page, and a search form
+below.  It should be possible to browse to the home page of an
+object without having detailed knowledge about the underlying
+mathematics.  The search form should be (at least partially) visible
+in a browser without scrolling the browse-and-search page.
+6. Home pages and browse-and-search pages should address the needs
+of both experts and non-experts in the subject, in order to ensure
+that the pages are useful to a broad mathematical audience.
