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; some 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, mail/news).
- Mozilla's RDF sitemaps were preceded by Meta 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 ancestor 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 1999 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 shared using SKOS. However it is not widely used to annotate in-page topic hierarchies. See CKAN list of datasets using SKOS.
- Google Rich Snippets have a 'breadcrumbs' construct, as does its successor
