The semantics of an XML document is …

[Roger L Costello <costello@mitre.org>]

Hi Folks,

The semantics of an XML document is determined by the actions taken on the XML document.

Consider this XML document:

<airplane-flight>
    <duration units="hours">1</duration>
    <speed units="kilometers-per-hour">500</speed>
</airplane-flight>

What is its semantics?

Answer: it has no semantics because it has no actions.

Pair up the XML document with actions that compute duration * speed (i.e., distance traveled by the airplane flight):

The semantics of the XML document is: 500

Pair up the XML document with different actions and it has different semantics:

Now the semantics of the XML document is: 310.686

Wicked cool!
