Files of records and file names

Files from all collection types

File directory on OCLC's server

The first part of a file name expresses the directory the files are in on OCLC's server.

Example: metacoll

Your library symbol

File names include your OCLC symbol. In the examples below, your OCLC symbol is represented as [XXX] in the examples.

Example: metacoll.[XXX].updates.D20160318.T210512.1.mrc

The collection's delivery frequency

The frequency of output is included in the file name. By default, records are output daily which is represented with a D before the date stamp.

Records for cataloging partner collections are output one time and file names include a D for Daily. For more details specific to files from cataloging partner collections, see files of records from cataloging partner collections.

Knowledge base collections, query collections, WorldCat holdings, and data sync collections have customizable delivery frequencies. Collections that have customizable delivery frequencies have options for Daily, Weekly, Monthly, or Quarterly record output. The frequency comes before the date stamp and is a letter: D, W, M, or Q.

The format, including the date stamp, is: DYYYYMMDD, WYYYYMMDD, MYYYYMMDD, QYYYYMMDD

Example: metacoll.[XXX].datasync.[provider].D20160318.T092700.bibdetailexcpt.1.mrc.txt

Date stamp

The date stamp expresses the date the file was output and includes the year, month, and date.

The date format is: YYYYMMDD

Example: metacoll.[XXX].datasync.[provider].D20160318.T092700.bibdetailexcpt.1.mrc.txt (The date stamp is 2016 March 18)

Time stamp

The time stamp expresses the time the system collected the data. The time stamp is Eastern Time and follows a 24-hour clock, including hour, minutes, and seconds. The letter "T" represents "Time."

The time format is: HHMMSS

Example: metacoll.[XXX].datasync.[provider].D20160318.T092700.bibdetailexcpt.1.mrc.txt (The time stamp is 9:27)

Example: metacoll.[XXX].datasync.[provider].D20160318.T000515.bibdetailexcpt.1.mrc.txt (The time stamp shows 5 minutes, 15 seconds after midnight, or 12:05.15)

File extensions .mrc and .xml

The file extension will be .mrc or .xml depending on the record standard you chose.

  • Record standards MARC 21 with MARC-8 and MARC 21 with UTF-8 Unicode will be output as .mrc files
  • Other record standard choices will be output as .xml files

 Note: Collection Manager output files older than 30 days are subject to being compressed (i.e., zipped) in order to improve performance. Compressed files are given the .zip extension but retain their original file name (e.g., metacoll.OCWMS.new.D20170612.T141740.1.mrc becomes metacoll.OCWMS.new.D20170612.T141740.1.zip).

See record standard settings in Record delivery.

Successive files in file sets

Files are output in chunks of no more than 100,000 records each. A numeric digit (.1, .2, and so forth) designates a file as one of multiple files output as a set.

Successive files will share the same date and time stamp. The extension keeps file names unique while allowing you to keep your set of records together.

Example of a set of records:

metacoll.[XXX].updates.D20160318.T210512.1.mrc (up to 100,000 records)

metacoll.[XXX].updates.D20160318.T210512.2.mrc (up to 100,000 records)

metacoll.[XXX].updates.D20160318.T210512.3.mrc (up to 100,000 records)

Records output in separate files

All WorldCat holdings and all serials in a separate file

If you choose (in your institutional-level settings) to have WorldCat Update records or records for all of your serial titles output in separate files, the file names will include text between the time stamp and the file extension.

Example of all WorldCat Update records in a separate file: metacoll.[XXX].new.D20160214.T210512.wcholdings.1.mrc

Example of all records for serials in a separate file: metacoll.[XXX].new.D20160214.T210512.ser.1.mrc

Records from a collection in a separate file with user-defined characters

If you choose (in the collection-level settings of one or more collections) to have individual collections output in a separate file, the file name you designated will be included.

Example from a cataloging partner: metacoll.[XXX].wcp.provider.D20160214.T210512.[YourFileName].1.mrc

Example from a knowledge base collection where the user entered RoyalCollegeofPsy as the name for the file:

metacoll.[XXX].new.D20160214.T210512.RoyalCollegeofPsy.1.mrc

It is possible to have more than one collection output to the same file by assigning the same file name for more than one collection. For example, if you have a knowledge base collection EBL DDA and a knowledge base collection EBL purchased, you can enter "DDA-and-purchased" in the delivery output field in both collections. You will get a file that contains records from both collections. Records will be distinguishable by collection name, collection ID, and collection notes (if you enter notes in each collect and map notes to your records in Customize Records).

Records that meet more than one qualification

If a record meets the qualifications to be output in more than one separate file, you could see more than one demarcation.

Example of a file with a serial title. The institution-level setting to have all serials output in a separate file is enabled. The user configured the collection to be output in a separate file with the name RoyalCollegeofPsy: metacoll.[XXX].new.D20160214.T210512.ser.RoyalCollegeofPsy.1.mrc

Files that designate a transaction type (new, updates, or deletes)

Transaction types are relevant to knowledge base collections, query collections, and updated records for your holdings in WorldCat.

Having the transaction type designated in the file name helps you maintain your records. Files are output in new, updates, or deletes folders on the server. Therefore, file names include new, updates, or deletes. See Criteria for records in new, update, and delete records.

Example:

metacoll.[XXX].new.D20160214.T210512.1.mrc

metacoll.[XXX].updates.D20160214.T210512.1.mrc

metacoll.[XXX].deletes.D20160214.T210512.1.mrc

Files of merged records

When two records are merged in WorldCat, Collection Manager will deliver an updated record if you have enabled MARC record delivery (regardless of whether you have enabled WorldCat updates).

Files of merged records will be delivered in a separate file that includes the word "merges" in the file name. If you enable the option for separate file delivery within a collection's record delivery settings, the file name will include both "merges" and the file name you defined.

All files of merged records will be delivered in Metadata > My Files. If you use FTP, merged records will be in the Updates folder.

Example file of merged records (default):

metacoll.[XXX].merges.D20160829.T183013.1.mrc

Example file of merged records for a file with separate file delivery:

metacoll.[XXX].merges.D20160829.T183013.YourFileName.1.mrc

Files of records for WorldCat updates

Files of updated records will include the word updates in the file name:

metacoll.[XXX].updates.D20150411.T104526.1.mrc

If you enabled the option to have all WorldCat updates in a separate file, the file name will include wcholdings:

metacoll.[XXX].updates.D20150810.T074419.wcholdings.1.mrc

Files of records from cataloging partner collections

Files of records from cataloging partner collections have wcp in the file name after your library symbol. Other variations in the file name are determined by the choices you have within each collection to customize the file name. If you enable book spine label otuput and choose to have your file of labels delivered to you rather than to your provider, you will get a file with lbl after your library symbol.

Records in files by provider (default)

metacoll.[XXX].wcp.[provider].D20160214.T210512.1.mrc

Firm and approval records in separate files by provider

metacoll.[XXX].wcp.FIRM.[provider].D20160214.T210512.1.mrc

metacoll.[XXX].wcp.APPR.[provider].D20160214.T210512.1.mrc

Records for a collection in a separate file

metacoll.[XXX].wcp.[provider].D20160214.T210512.[YourFileName]1.mrc

File of labels

If you chose to have labels output for titles in a cataloging partner collection, you will receive a file of labels if you also chose to have the files come to you rather than to your provider.

Example: metacoll.wcp.[XXX].lbl.[provider].D20160214.T210512

Files of records from data sync collections

Files of records from data sync collections have datasync in the file name after your library symbol.

Example: metacoll.[XXX].datasync.D20160214.T210512.WorldCatRecords1.mrc
