Change catalog_item to dataset

Project Open Data: http://project-open-data.github.io/schema/ as well as DCAT http://www.w3.org/TR/vocab-dcat/ as well as Schema.org http://schema.org/Dataset as well as CKAN, the most popular open source data portal, as well as Socrata, the most popular closed source data portal: https://opendata.socrata.com/ as well as at least two projects on Drupal.org DKAN and CKAN all use a "dataset" for what this project seems to be calling a "catalaog_item". Can "catalog_item" be changed to "dataset"?
