MetaCard
discontinued cross-platform, commercial HyperCard clone

MetaCard is a discontinued cross-platform, commercial HyperCard clone. MetaCard included an IDE, a GUI toolkit and had its own language, MetaTalk. From the MetaCard Corporation website: "The MetaTalk language has all the features common to third-generation languages like C/C++/Java but has a much simpler syntax."
Cross Worlds Computing developed applications on the MetaCard platform (e.g., Ten Thumbs Typing Tutor) and developed their own MetaCard IDE called Revolution. They agreed to take over MetaCard development adding the language and runtime to Revolution and changed their name to Runtime Revolution (RunRev). RunRev did not adapt the original MetaCard IDE and it was made available as free and open-source software via a Yahoo! group and a RunRev hosted mailing list. Runtime Revolution changed the name of Revolution to LiveCode and then changed their name to LiveCode, Ltd. as well.
Begin with the source’s own compact description: “MetaCard” is discontinued cross-platform, commercial HyperCard clone. The dossier treats that line as a proposition to test through MetaCard, discontinued and cross-platform, not as a finished interpretation.
Why this record matters
The phrase “discontinued cross-platform, commercial HyperCard clone” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 9, 2022. The linked authority identifier is Q6822271. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
