Offhand sketch for object model of unspecific quality

Ed. Note: The web-based "WYSIWYG" editor for Google's Blogger service does not handle "angle brackets" very well. One must enter the character entities "&<" and "&>" manually. So, here is edition 3 of this article. now partially un-mangled via the "WYSIWYG" editor. The "WYSIWYG" blog entry editor had nearly destroyed this item, when its first edition was published.

• e.g. To sometime answer a question, perhaps: "Why is 'op-amp' just denoted as an annotation, there?"
• GUI
• Desktop Applications
• Mobile/Thin Client Applications
• "Workshop" Applications

Why this is just in an outline format:

• This article is presently a sidebar beside some fairly tedious "Lab work".
• in which exactly one UA741CP is applied, together with a total of four ratings of resistor, one linear potentiometer, a DC power supply, and the inevitable LED
• Why "So unspecific"
• Because it's an unspecific design, presently
• But really not to be presented for easy rip-off by touring entertainers.
• Unpublished "Previous work"
• Annotation object model for Common Lisp (design sketch)
• One may as well develop some kind of a SLIME-contrib extension for it, one supposes 
• to "hide the angle brackets," for instance, 
• instead, to display the annotations for, each, their "Preferred label"
• with annotation-of-annotation, namely for purpose of recording:
• author of annotation
• time when annotation was created
• time when annotation was last edited (linked with object/annotation edit history)
• author of last edit (linked with object/annotation edit history)
• ...in a database of sufficient extensibility to be able to record such things, in a generic regards, and with a free-open source platform in the same -- noting that Java's community process is probably an important part how Java has survived the acquisition by Oracle, the acquisition of Sun Microsystems.
• integrating with SKOS
• in Common Lisp
• for "Such as this" and not only "Such as this"
• also because literature
• and language
• and does one mention, language?
