How long will data be stored in CaltechDATA?

In most cases, indefinitely.  Any data that violate the Terms of Deposit or which fails to meet minimum standards for retention may be withdrawn. For example, we may eventually remove deposits that consist of unusable/obsolete files or are inadequately described. Files that are larger in size may have higher standards for retention.  The DOI for all records will be retained and will lead to a tombstone page listing the reason for withdrawal.

How much data can I store on CaltechDATA?

There are currently no hard storage limits, but you should only deposit data that will be useful to others.  All data must be described in sufficient detail so that others can understand it.  If you're planning on uploading more that 500 GB of data, please data [at] caltech.edu (subject: Uploading%20Large%20Amounts%20of%20Data%20to%20CaltechDATA) (contact us) first.

 

Does CaltechDATA have any file size restrictions?

No, but file size can impact the availability of files.  Files under 1GB will always be immediately available.  Files under 100GB may be immediately available only if they are accessed every four months.  Otherwise files may be stored on Infrequent Access Storage (IAS) and may take up to 24 hours to retrieve.

 

How do I access my CaltechDATA files in Infrequent Access Storage(IAS)?

Currently no files are stored on IAS.  When this feature becomes active, instructions will be provided.

 

Can I make my files in CaltechDATA private?

Not indefinitely.  You can embargo data for a specific period of time, but all data must be intended for public access at some point in the future.

 

Can I restrict data in CaltechDATA to specific users or groups?

No, CaltechDATA is an open repository.

 

Does my data need to be published before uploading to CaltechDATA?

No, you can upload unpublished data.  If you wish, you can embargo the data until publication.  You can easily link your data to publications by entering the DOI in the related publications field.

 

What metadata fields are used in CaltechDATA?

Our metadata is derived from the DataCite 4.0 schema, and is compliant with the Project Open Data 1.1 schema (used by US Federal Government Agencies).  Our metadata includes an explicit related publications list.

What can I do with data in CaltechDATA?

You can use the read API to load files in CaltechDATA into another application.  For example, the web application at plots.caltechlibrary.org  allows you to interactively plot two mineral spectra files (https://data.caltech.edu/records/208, https://data.caltech.edu/records/209).  You can see the api code that generates this demo at https://github.com/caltechlibrary/caltechdata_plot.  Feel free to send us an email at data [at] caltech.edu if you'd like help integrating the repository with your application. 

Is there any charge for storing data in CaltechDATA?

CaltechDATA storage is provided by the library at no cost in most cases.  Users planning on depositing more than 500 GB of data should email us at data [at] caltech.edu to discuss your requirements.
