What is an API *legally*?
Authored by: Ed L. on Saturday, April 21 2012 @ 10:07 AM EDT
And, also, an API in programming terms *is* a header file.
Really? For C, perhaps. Part of a header file, at least. But C++?? Or Java???.

Seriously. We'll have to do better than that. To repeat an earlier comment,

Here now we have Judge Alsup tasked with determining whether or not an "API" may be protected by copyright. So the judge needs a legal definition of what is an API, both in the specific sense of a Java API, and if possible, in a general sense that might be misapplied to all programming languages, past, present, and as yet unnamed.

Sounds so far as if Google would like a very narrow definition e.g. "A Java class API *is* the class interface", whereas Oracle would like something more vague and general and creative. In particular something involving documentation.

Judge Alsup's decision on this one will reach far beyond Java, so its important he formulates a "What is an API" definition that meets with general industry and academic consensus.

This is indeed murky. Hence the Judge's request for additional briefs. What should they entail?

An API is a Standard
Authored by: vonbrand on Saturday, April 21 2012 @ 10:16 PM EDT

I happen to think that the "plane cockpit" example given to PJ is right on the money on APIs. It is the "naming" (in the cockpit case, the form and color of the buttons, the shape and markings on the dials, the color of the blinkenlights) and their "meanings" (semantics; what happens if you press a button or move a lever, what each dial shows in what units, what light is lighted when). Sure, the overall layout is important too for familiarity, but you could move stuff around and an experienced pilot shouldn't be too lost. In the case of Java APIs the overall layout would be more or less the grouping of classes in packages.
