(on Format, Collection) A list of words or short phrases that describe important features of this object, useful for searching.
The core of IMDC is the Collection object. A Collection is a set of closely related data files, usually collected as part of a single effort. A Collection may contain other Collections or Publications to indicate that it contains all the data contained by the others. For example, Collections named “F-root DNS traces” and “A-root DNS traces” might each contain hundreds of data files representing traces taken at the respective root DNS servers, while “Root DNS traces” might contain both of those Collections and thus indirectly contain all data contained by those Collections.
A Publication describes a scholarly paper, article, or other publication that uses Internet measurement data. IMDC is not meant to be a catalog of publications, as that service is already performed by other sites such as Google Scholar and CiteSeer. Rather, the primary purpose of indexing publications in IMDC is to index the data used by the publications. A Publication object in IMDC can be thought of as a specialized kind of Collection representing the data used by the publication. Like a Collection, a Publication may contain other Collection or Publication objects in order to incorporate their contents.
A Location object represents a method for obtaining a Collection of data. Collections available via multiple means (e.g., mirrors) will have a distinct Location object for each. Often a Location will include a URL linked directly to a collection directory (external to IMDC), although it may be password-protected or otherwise restricted. If the Location is restricted in any way, such as requiring owner approval or agreement to an AUP, there will be instructions on how to proceed.
Contact objects describe a person or role. Contacts are used to describe the creators of collections and other cataloged items. Every IMDC login account is also a Contact.
(on login accounts only) A unique string of 3-80 non-space characters used to log in to IMDC.
(on login accounts only) A secret string of 4-40 characters.
(on login accounts only) An address at which IMDC can send email to the user. This address will never be given out to anyone else. When an account is created, this address will be subscribed to IMDC mailing list(s); but if you wish to change the address used for a mailing list later, you must visit the mailing list pages directly.
(on login accounts only) The user's preferred time zone. This is used for displaying and optionally inputting dates and times.
“person” if this contact describes an individual person (e.g. “John Smith”), or “role” if this contact describes a job or function independently of the person or people who perform it (e.g. “FooNet Data Manager”).
An email address that will be given out to other users.
The contact's phone number. You may choose to hide this from other users.
The contact's postal address. You may choose to hide this from other users.
The contact's country. You may choose to hide this from other users.
A Data Format (e.g., “pcap”) describes the file format used by raw data files, and a Package Format (e.g., “tar-gzip”) describes the file format used to bundle multiple data files together into a single file.
Describes whether the file format is binary, text, or mixed.
A set of suffixes commonly used on the names of files of this format (e.g., “.pcap” or “.tar.gz”).
