This article is a stub. You can help the microformats.org wiki by expanding it.
This page is a collection of research regarding previous breadcrumbs formats towards the development of a breadcrumbs vocabulary and microformat per the process.

- Late-90s Mozilla/Netscape browser had built-in understanding of a sitemaps format expressed in RDF. Technical details are likely buried in Mozilla CVS [press releases still survive]. The vocabulary encoded a sitemap as a graph structure, using a 'child' property to represent hierarchy, as in other areas of Mozilla (e.g. [see Mozilla docs], [[1]]).
- Mozilla's RDF sitemaps were preceded by [Content Format] (MCF) sitemaps (Netscape took MCF from Apple ~1997). MCF sitemaps described a site hierarchy using a network of linked text files that summarised the site structure. MCF was an [[2]] of both RSS and RDF.
- ILRT / University of Bristol had a server-based implementation of the same format (now code-rotted), and experiments with alternatives that instead used more HTML concepts: see [draft spec]
- more recent work around RDF has focussed on describing hierarchies of topics using the [SKOS vocabulary]; this has gained significant traction in the library community, and many thesauri are now shared using SKOS. However it is not widely used to annotate in-page topic hierarchies. See [list of datasets using SKOS].
- Google Rich Snippets [a 'breadcrumbs' construct], as does its [successor]
