- Knows Hypertext Transfer Protocol, or HTTP (1991+), as the basic technology for resolving hyperlinks and transferring data on the World Wide Web.
- Understands that Linked Data (2006) extended the notion of a web of documents (the Web) to a notion of a web of finer-grained data (the Linked Data cloud).
- Knows the "five stars" of Open Data: put data on the Web, preferably in a structured and preferably non-proprietary format, using URIs to name things, and link to other data.
- Reuses published properties and classes where available.
- Understands trade-offs between "opaque" URIs and URIs using version numbers, server names, dates, application-specific file extensions, query strings or other obsoletable context.
