Information about the distributor of and options for obtaining the data set.
The party from whom the data set may be obtained.
The identifier by which the distributor knows the data set.
Statement of the liability assumed by the distributor.
The common ways in which the data set may be obtained or received, and related instructions and fee information.
The description of options for obtaining the data set on non-computer-compatible media.
The description of options for obtaining the data set on computer-compatible media.
Description of the form of the data to be distributed.
The name of the data transfer format.
Version number of the format.
Date of the version of the format.
Name of a subset, profile, or product specification of the format.
Information about the content and format of an ASCII data file.
The character(s) which indicate the end of a record.
The number of lines at the beginning of the file before the data content actually begins.
Description of the information content of the header lines.
Definition of the direction of information content as represented in the ASCII file. Typical data sets are represented in column-major format, where each attribute in the data set is represented as a column and each observation is a row. In contrast, row-major data sets represent attributes as rows and observations as columns.
If the content of the data set is encoded in case-sensitive ASCII (the capital and small letters have meaning), then this element should contain 'y' or 'Y', otherwise this element should contain 'n' or 'N'.
Information allowing verification of file contents to ensure accurate transmission of the file. This is generally a named checksum that uses a standard algorithm or a cryptographic signature. For example, a MD5 checksum could be provided and, if it matches a MD5 checksum calculated for the received file, one would conclude that the file is identical to the original.
Character used to quote fields in the data representation so that the field delimiter can be used as part of the field value. This character is typically a single quote mark or double quote mark.
Information describing the individual data fields (this would be equivalent to columns in most databases).
Name of the data field. This name should be the same as an Attribute Label documented in Section 5.1.2 Attribute (within Detailed Description which is itself within Entity and Attribute Information). The definition, domain, units of measure, and measurement resolution are all important pieces of information for ASCII file use.
The code which represents missing data.
The character which indicates the end of the data field contents.
The number of characters of the data field.
Description of the content of the data encoded in a format.
Recommendations of algorithms or processes (including means of obtaining these algorithms or processes) that can be applied to read or expand data sets to which data compression techniques have been applied.
The size, or estimated size, of the transferred data set in megabytes.
The means and media by which a data set is obtained from the distributor.
Information required to directly obtain the data set electronically.
Instructions for establishing communications with the distribution computer.
The electronic address from which the data set can be obtained from the distribution computer.
The name of the file or service from which the data set can be obtained.
Information required to access the distribution computer remotely through telephone lines.
Lowest or only speed for the connection's communication, expressed in bits per second.
Highest speed for the connection's communication, expressed in bits per second. Used in cases when a range of rates are provided.
Number of data bits in each character exchanged in the communication.
Number of stop bits in each character exchanged in the communication.
Parity error checking used in each character exchanged in the communication.
Data compression available through the modem service to speed data transfer.

The name of a file containing the data set on the distribution computer.
Instructions on the steps required to access the data set.
The brand of distribution computer and its operating system.
Information about media-specific options for receiving the data set.
Name of the media on which the data set can be received.
The density of information to which data are written. Used in cases where different recording capacities are possible.
The density in which the data set can be recorded.
The units of measure for the recording density.
The options available or method used to write the data set to the medium.
Description of other limitations or requirements for using the medium.
The fees and terms for retrieving the data set.
General instructions and advice about, and special terms and services provided for, the data set by the distributor.
Typical turnaround time for the filling of an order.
Description of custom distribution services available, and the terms and conditions for obtaining these services.
Description of any technical capabilities that the consumer must have to use the data set in the form(s) provided by the distributor.
The time period when the data set will be available from the distributor.
