I'd like to store some information about some items, where each item has a set of attributes. Something like:

Car
   Wheels=4
   Doors=4
   Color=Blue
Bike
   Wheels=2
   Color=Red
[download]

In the actual data, there'll be between 20-30 attributes for each item. Some items don't use certain attributes, those would either be left out entirely or just set to a null value.

I could use a hash for each attribute and access it with $Color{"Car"}, or use a hash of hashes, but is there a really nice neat way to do stuff like this? Am I treading so close to OOP that I just need to take the plunge now?

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
