Frequently Asked Questions about CRAWDAD

Q: How can I download CRAWDAD datasets or tools?
A: You first need to register for full access to CRAWDAD data/tools to obtain a user ID/password. You can find download links on each dataset/tool page (e.g., dartmouth/campus). Clicking a link and entering your ID and password will start the download.
Q: What policy applies to use of CRAWDAD datasets?
A: Please refer to the Data license agreement to which you must agree when registering as a CRAWDAD user. The terms of this agreement are, at their core, straightforward but important: acknowledge (cite) the dataset contributors, don't de-anonymize any persons whose data is in the dataset, and don't re-share the dataset - direct interested persons to CRAWDAD. Thanks!
Q: How do I open the datasets or tools?
A: The datasets are of varying formats depending on what was collected and who contributed the data. Some common formats include CSV, libpcap or gzipped tar files. You can find more information on the metadata page for each dataset.
Q: How should I cite CRAWDAD data or tools in my paper?

A: When you write a paper that involves the use of CRAWDAD datasets or tools, we would appreciate it if you can cite the dataset (as well as acknowledge CRAWDAD). For example, "We used the dartmouth/campus dataset [1] from CRAWDAD for the analysis in Section 4. We collected our SNMP data using the tools/collect/snmp/snmputil tool [2] from CRAWDAD."

We provide BibTeX and RIS (see an example of BibTeX below) at the bottom of each metadata page (e.g., dartmouth/campus) so that you can easily cite CRAWDAD resources:

        author = {David Kotz and Tristan Henderson and Ilya Abyzov and Jihwang Yeo},
        title = {{CRAWDAD} dataset dartmouth/campus (v. 2009-09-09)},
        howpublished = {Downloaded from},
        doi = {10.15783/C7F59T},
        month = sep,
        year = 2009

If you do not use BibTeX or RIS, we ask that you include a reference with the same information: authors, title and version of the dataset, date, and the DOI and URL where people can find the data or tool. You can find more information on why one should cite data in the Force11 Joint Declaration of Data Citation Principles. Please don't just say “we used CRAWDAD datasets” or similar; we have over 130 datasets and vague citations won't help readers understand your work!

Furthermore, if you could add the paper to our Zotero library or send us a copy or pointer to your paper, it would be most appreciated. Not only does that help other users of the data but it helps you by advertising your paper to an interested audience.

You can find out more about data citation practices in our article in D-Lib Magazine.
