The ONIX Document Type Definition (DTD) contains in its entirety over 230 data elements and composite elements, organized into 38 groups. Of these groups, 25 relate to product records, 6 to main series records and 7 to sub-series records.
Creating and Transferring ONIX Files
First, organize your book data into ONIX-specified fields and store it in a database. This can be done by using the BNC Bronze Template. Then, use the BNC ONIX Converter to organize and tag that data, thus creating an ONIX file.
The simplest way to transfer your data is via the Internet by way of an email attachment or FTP (file transfer protocol). First time submissions which contain an imprint or publisher name and new code may also need to be accompanied by an Excel or text file that lists the imprint or publisher's name and corresponding code. This will ensure that the codes are associated with the correct buying channels for purchasing. The retailer or distributor verifies the data and then translates it into the information you see on a web page.
