I believe the second category is usually called "metadata" - information about information. From Wikipedia's Metadata article:

Metadata (meta data, or sometimes metainformation) is "data about other data", of any sort in any media... Metadata may include descriptive information about the context, quality and condition, or characteristics of the data.

Some tips about writing meditations and SOPWs:

• If your post only poses a question, it should go in SOPW. To turn it into a meditation, one needs to add some personal insights, reflections, or citations and analysis from third party sources.
• The post should make clear how it relates to one or more of the following: (a) Perl (b) the art and/or profession of programming (c) the community life of Perl Monks. (Note: Posts that are primarily related to community life should be placed in PerlMonks Discussion rather than Meditations). I don't think you have done that here. If you feel this is related to any of those three topics, perhaps you might want to expand on the original post content?
• Sometimes people do ask questions that aren't just about the above three topics. If so, your post should be named "OT: actual title here". Also it is a good idea to explain why you have chosen to ask an off-topic question. From time to time people do post off-topic questions simply because they have grown comfortable with this community and want its feedback.

Best, beth
