Changes and Updates to Naxos MARC.XML - Updated 10.23.13

Since the launch of the complete Naxos Music Library and Naxos Music Library-Jazz MARC.xml, we've received some great feedback! Below I've provided a change-log, as well as some screenshots. These changes were made to allow for the .XML to be batch (and singly) imported into MarcEdit easier.

The URL's for download have been updated, and are included below, as well as on our previous blog post.

Download Links

Naxos Music Library - 22.2MB

Naxos Music Library - Jazz - 1.9MB

Previous .xml will reference utf-16 encoding, and not include any style schema

Previous .xml will include extra white space, thus creating a new line in some cases. We've removed this to allow for ease of import via MarcEdit

We added some .xml schema specifications, and altered the UTF encoding from utf-16 to utf-8

We updated the 856 field and removed the white space causing a newline (error) in some cases

Changelog

1. "utf=16", changed to "utf=8"

2. Added - <... xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.loc.gov/MARC21/slim http://www.loc.gov/standards/marcxml/schema/MARC21slim.xsd">

3. White space/Newline removed from 856 field

Batch Conversion of (Naxos) .xml to .mrc

We've also had folks inquire about the general process for "batch conversion of MARC .xml to .mrc. The process for that, as it pertains to the Naxos MARC .xml, is included below with screenshots.

While we at Naxos excel at many things, the use and intricacies of MarcEdit are not among them. If you have specific MarcEdit function questions, you are best served directing them to the appropriate party/parties.

In MarcEdit's "MARC Tools" module:
1. Click Tools, then Batch Process Records

This process may differ depending on the version of MarcEdit you have installed. For further information, consult the MarcEdit help section.

2. Find and select the folder that contains the entire .xml for import. In my example to the right, the file is titled "Small Sample".

Your filename will likely be "NML-MARC-XML-US" - or something very similar.

Lastly - be sure to enter ".xml", without the quotes, in the File Types box.

3. Select the function you're interested in having MarcEdit perform.

In our case, it's "MARCXML to MARC".

Once complete, your screen should look similar to the one to the left.

4. Viola! You should now see a folder titled "processed_files" in either your specified location, or within the previous folder selected.

If your conversion was successful, not only will you receive a confirmation from MarcEdit, but also the files should look similar to the right. Again, I used a small sub-section of the records for our purposes here.

MARC .XML Now Available for Naxos Music Library Subscribers

We're happy to announce that a complete set of Naxos Music Library and Naxos Music Library-Jazz MARC.XML records are now available! The links for download and a plethora of information are below. Please save this message for future reference, as it contains answers to most the common questions we've received in the past.

Download Links
Naxos Music Library
Naxos Music Library-Jazz

The data is complete and up-to-date as of October 1, 2013. Going forward, these links will be updated quarterly, so be sure to check back shortly after January 15, 2014 for the next update! We'll also send out a notice that the records/links have been updated.

What format are the records in?
The above links provide standard MARC.XML (MARC21) data. This data can be ingested directly into most catalog systems without issue. The records are made available on an "as-is" basis, and as an end user you or your colleagues are free to make any changes to the data, records, fields, and/or presentation as you see fit, locally.

Above is a small sample of a record.
Download the full batch above to evaluate the complete records for yourself!

MARC 21 XML General Information
*Note that portions of the LOC website may be unavailable or will not be updated during the U.S. Government appropriations shutdown (as of Oct. 1, 2013).

What should the data look like when extracted?
The files extract into year-based folders. Each year includes the files/data for albums made available in NML that year.

This is how the files should appear, after successful extraction.

Record Count - As of October 1, 2013
Naxos Music Library - 62,342
Naxos Music Library - Jazz - 7,132

Why don't the record counts match the disc counts on the site?
The disc counts on NML are just that - disc counts! Since the MARC.XML are generated based on catalog ID, some of which contain multiple discs, you may see some discrepancy in the numbers between the site's "disc counts" and the number of records. This is normal and intended - rest assured that all discs are accounted for.

Does the 856 field need to be updated?
No! Unlike previous incarnations, this data set deploys some long-awaited technology. The URL included in the MARC files will now automatically detect the account with which you're associated (based on your IP address) and transform the link correctly. This is a great opportunity to ensure you've got the most up to date IP information in our system! Contact us to ensure everything is on file correctly.

Should you wish to customize the URL to include specific proxy information, you only need to replace the portion of the URL below in all caps (UNIVPORTAL). The rest of the URL will perpetually remain as is. No more updating the URLs annually!

Example URL Alteration
http://UNIVPORTAL.naxosmusiclibrary.com/catalogue/item.asp?cid=8.573027

With a prefix-based proxy augmentation:
MyProxyInformation.naxosmusiclibrary.com/catalogue/item.asp?cid=8.573027

With a suffix-based proxy augmentation:
MySubdomain.naxosmusiclibrary.com.MyProxyInfo/catalogue/item.asp?cid=8.573027

If you encounter any difficulties in updating the 856 field URLs, please don't hesitate to contact your local Naxos representative anytime. If you're unsure who that would be - you can find out easily right now.

Any Known Issues?
There is currently a known issue with using Google Chrome for some downloads. At present, even though all of the data has been delivered Chrome will hold the transfer session open for longer than intended. If this occurs, simply allow the download to finish. It can take between 1 and 5 minutes for this process to complete. Canceling and restarting will have the same end effect.

Here's an example of what the open-transfer may look like when using Chrome.

7-Zip Compression
Since the data files are so large when unpacked (over 1.1GB), we needed a compression format that would allow for immense compression. 7-Zip (.7z) is the answer! Should you not have the capability at present, I've included links for PC and Mac below. Each of these archivers will handle 7-Zip with ease and are free of charge, without restrictions on use.

We welcome your feedback in any way, shape, and form, so please let us know if you have any questions, comments, or would like to discuss the MARC records further.

Happy MARC'ing!
