That's exactly what W3C's DCCI does [1]: a DOM of system-properties.
Yet, I don't think that that specification was ever implemented, let
alone used, probably because the concept of a DOM of properties is too
obscure for your basic system-property query (battery level, CPU load,
etc.). You don't want to start exploring a hierarchy, let alone use DOM
functions, you just want a function.
IMO the SysInfo API is a framework, an abstraction on top of either a
DCCI or a REST implementation. Even more abstract than JQuery, if you like:
SysInfo
|
JQuery
/ \
DCCI REST
You can either you write your Battery Monitor using bare-bones DCCI (see
[1] appendix B to get an idea) or XHR, or you make it simpler for
yourself with JQuery:
$.dcci("device battery", callback) if based on DCCI
$.get("device://battery", callback) if based on REST
or top-level-abstract-framework-agnostic:
navigator.sysinfo.get("Battery", callback)
