I determined how to install the modules and got Jason Casden's script to work.  (Thank you Jason Casden where ever you are!)  The script does a great job at normalizing the dates, but I noticed it doesn't add a type attribute (inclusive or bulk).  

The type attribute didn't cross my mind before.  For all those normalizing dates at the file level, are you also adding the type attribute?  What are the pros/cons for including or excluding it?

I don’t know about Active Perl but with regular perl there’s no install necessary, you just put the two files ( and into the correct directories, so the script can find them when it runs.

Thank you everyone for your responses!  Most who shared are normalizing dates (or wish they were).  I'm going to look more closely into Jason Casden's PERL script, but I haven't worked much with PERL before.  I installed ActivePerl, but can anyone advise me on installing the necessary XML::Twig and HTML::Entities modules?  I found the website for XML::Twig, but don't know how to install it as a module.


Thanks again; this is a great list!

Good morning,


I'd like to take a quick and extremely informal survey.  How many institutions are normalizing dates at the file level?  My past institution only normalized dates at the top, series, and subseries levels.  The rational was that it's not worth the time to normalize at the file level because there aren't enough publishing options available that utilize the data.  (Plus, there's a script to normalize dates if it's needed.)  My current institution is looking at best practices for our encoding and I'd be interested to hear what others are doing .
