Metaobject
In computer science, a metaobject is an object that manipulates, creates, describes, or implements objects (including itself). The object that the metaobject pertains to is called the base object.

<World-Wide Web> An element, with tag name of "META",
expressing meta-data about a given HTML document. HTML
standards do not require that documents have META elements;
but if META elements occur, they must be inside the document's
HEAD element.
The META element can be used to identify properties of a
document (e.g., author, expiration date, a list of key words,
etc.) and assign values to those properties, typically by
specifying a NAME attribute (to name the property) and a
CONTENT attribute (to assign a value for that property). The
HTML 4 specification doesn't standardise particular NAME
properties or CONTENT values; but it is conventional to use a
"Description" property to convey a short summary of the
document, and a "Keywords" property to provide a list of
keywords relevant to the document, as in:
<META NAME="Description" CONTENT="Information from around the
world on kumquat farming techniques and current kumquat
production and consumption data">
<META NAME="Keywords" CONTENT="kumquat, Fortunella">
META elements with HTTP-EQUIV and CONTENT attributes can
simulate the effect of HTTP header lines, as in:
<META HTTP-EQUIV="Expires" CONTENT="Tue, 22 Mar 2000 16:18:35 GMT">
<META HTTP-EQUIV="Refresh" CONTENT="10; URL=http://foldoc.org/">
Other properties may be application-specific. For example,
the {Robots Exclusion
(http://info.webcrawler.com/mak/projects/robots/norobots.html) }.
standard uses the "robots" property for asserting that the
given document should not be indexed by robots, nor should
links in it be followed:
<META NAME="robots" CONTENT="noindex,follow">

Metaobject
In computer science, a metaobject is an object that manipulates, creates, describes, or implements objects (including itself). The object that the metaobject pertains to is called the base object. Some information that a metaobject might define includes the base object's type, interface, class, methods, attributes, parse tree, etc. Metaobjects are examples of the computer science concept of reflection, where a system has access (usually at run time) to its own internal structure. Reflection enables a system to essentially rewrite itself on the fly, to alter its own implementation as it executes.
