e-Resources - Policies

I. Introduction

e-Resources is Thermal-Fluids Central's open repository. It collects, preserves, and disseminates, securely and reliably, the intellectual and creative digital works of its contributors, allowing their research to reach a wider audience than traditional forms of distribution.

The following policies and guidelines outline various aspects of depositing and managing content in e-Resources. These policies and guidelines are subject to internal review and modification. e-Resources communities will be alerted to any changes which affect them or their collections in the institutional repository.

II. Content Guidelines

e-Resources contains the following types of documents produced by the thermal-fluids community:

  • Lectures
  • Animation and Video
  • Presentations
  • Research Database
  • Workshops
  • Simulation Tools

In addition, the following requirements must be fulfilled to deposit material in e-Resources:

  • Content must be produced, submitted, or sponsored by e-Resources' contributors.
  • Content must be scholarly, educational, or research oriented.
  • Content must be digital.
  • Content must be complete and ready for distribution.
  • The author/creator must be able and willing to grant e-Resources the right to preserve and distribute the work including fulfilling publisher conditions for depositing works and clearing copyright permissions when appropriate.

III. Community and Collection Policies

e-Resources content consists of collections maintained within communities. These collections will be subject to guidelines defined by Global Digital Central administration, and any changes made will be done so at the discretion of Global Digital Central. As in all partnerships, it is important that all stakeholders understand and agree to the policies, guidelines, and procedures required to build an open repository.

What is a e-Resources Community?

e-Resources consists of collections submitted by contributors in the field of thermal-fluids. An e-Resources community is a general content category for e-Resources items, such as lectures, presentations, or animation/videos.

What is a e-Resources Collection?

The actual contributions to e-Resources are stored within collections, which are located within communities and sub-communities. e-Resources collections are divided into more specific categories than their parent communities, and focus on individual topics within the field of thermal-fluids.

IV. Non-exclusive Deposit License

When depositing items in e-Resources, a non-exclusive deposit license agreement appears in the submission template. This grants e-Resources the right to distribute scholarly works online and to migrate them to new formats in the future if necessary. Authors must agree to the terms of this license to complete the submission by clicking the "I Grant the License" button. If someone deposits items on an author's behalf, the proxy will grant the license and the author will be bound to the terms.

Here is the license as it appears in the submission template:

	      By signing and submitting this license, you (the author(s) or copyright
	      owner) grants to e-Resources the non-exclusive right to reproduce,
	      translate (as defined below), and/or distribute your submission (including
	      the abstract) worldwide in print and electronic format and in any medium,
	      including but not limited to audio or video.
	      You agree that e-Resources may, without changing the content, translate the
	      submission to any medium or format for the purpose of preservation.
	      You also agree that e-Resources may keep more than one copy of this submission for
	      purposes of security, back-up and preservation.
	      You represent that the submission is your original work, and that you have
	      the right to grant the rights contained in this license. You also represent
	      that your submission does not, to the best of your knowledge, infringe upon
	      anyone's copyright.
	      If the submission contains material for which you do not hold copyright,
	      you represent that you have obtained the unrestricted permission of the
	      copyright owner to grant e-Resources the rights required by this license, and that
	      such third-party owned material is clearly identified and acknowledged
	      within the text or content of the submission.
	      e-Resources will clearly identify your name(s) as the author(s) or owner(s) of the
	      submission, and will not make any alteration, other than as allowed by this
	      license, to your submission.

V. Access Policy

All items in e-Resources will be considered free for all to view, in accordance with standard "open access" principals, unless otherwise negotiated with e-Resources administrators.

VI. Withdrawal Policy

Global Digital Central foresees under exceptions times that it may be necessary to withdraw items from e-Resources. Under some circumstances items will be removed from view, but to avoid loss of the historical record, all such transactions will be traced in the form of a note in the < Description.provenance > field of the Dublin Core record. The content of the note will be one of the following:

  • removed from view at request of the author
  • removed from view at e-Resources' discretion
  • removed from view by legal order
  • removed from view at the community's discretion

Since items that are removed may have been cited, e-Resources will always supply a "tombstone" when the item is removed, which will include the original metadata for verification plus one of the above withdrawal statements in place of the link to the object. The metadata will be visible, but not searchable, and is unavailable for metadata harvesting.

VII. Format Support

We wish to provide support for as many file formats as possible. Over time, items stored in e-Resources will be preserved as is, using a combination of time-honored techniques for data management and best practices for digital preservation. As for specific formats, however, the proprietary nature of many file types makes it impossible to guarantee preservation. Put simply, our policy for file formats is:

  • Everything in e-Resources will be retrievable.
  • We will recognize as many file formats as possible.
  • We will support as many known file formats as possible.

When a file is uploaded to the IR, we assign it one of the following categories:

  • supported: we fully support the format
  • known: we can recognize the format, but cannot guarantee full support
  • unsupported: we cannot recognize a format; these will be listed as "application/octet-stream," aka, Unknown

By "support" we mean "make usable in the future, using whatever combination of techniques (such as migration, emulation, etc.) is appropriate given the context of need." For supported formats, we might choose to bulk-transform files from a current format version to a future one, for instance. Because we can't predict which services will be necessary in the future, we continually monitor formats and techniques to ensure we can accommodate needs as they arise.

In the meantime, we can choose to support a format if we can gather enough documentation to capture how the format works. In particular, we collect file specifications, descriptions and code samples and make those available in the e-Resources Format Reference Collection below. Unfortunately, this means that proprietary formats with non-public materials cannot be supported in e-Resources.

We will still preserve these files, however, and in cases where such formats are native to tools supported by e-Resources, we will provide you with guidance on converting your files into formats we do support. It is also likely that the popularity of some proprietary formats (such as Microsoft .doc, .xls, and .ppt) will ensure their continued prevalence or at least the tools to convert such formats to new ones. Even so, we cannot guarantee this level of service, so we will still list these formats as "known," not "supported."

What to do if your format isn't recognized

We understand that there are always more formats to consider, and we would appreciate your help in identifying and studying the suitability of support for formats you care about. If we can't identify a format, e-Resources will record it as "unknown," aka, "application/octet-stream," but we would like to keep the percentage of supported format materials in e-Resources as high as possible.

e-Resources Format Reference Collection

In the table below, description is what most people use as the name for the format. Extensions are typical file name extensions (the part after the dot, e.g., the extension for "index.html" is "html"). These are not case-sensitive in e-Resources, so either "sample.XML" or "sample.xml" will be recognized as XML. MIME type is the Multipurpose Internet Mail Extensions (MIME) type identifier. Level indicates e-Resources's support level for each format:

  • supported: we fully support the format
  • known: we can recognize the format, but cannot guarantee full support
  • unsupported: we cannot recognize a format; these will be listed as "application/octet-stream," aka Unknown
