erc - command to lookup Electronic Resource Citation metadata tags
erc utility is currently a simple interface to the query metadata tags from the ERC vocabulary. Its one sub-command, get, receives zero or more tag arguments, which are either numbers, element names, or regular expressions. Given one or more tags, it prints the corresponding ERC element name, a tab, and its semi-numeric code, one per line. With no arguments, get prints all known names in hash table order (which tends to look random).
A tag given as a non-negative integer, possibly preceded by a letter, will usually be looked up as a semi-numeric code. If the tag looks like a regular expression, it will be used to search among element names. Otherwise the tag will be looked up as an element name. The return status will be 1 if any requested code is not known.
