We want to provide support for as many file formats as
|
|
possible. Over time, items stored in DSpace 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 much more than this. Put
|
|
simply, our policy for file formats is:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>everything put in will be retrievable</li>
|
|
<li>we will recognize as many files' formats as possible</li>
|
|
<li>we will support as many known file formats as possible</li>
|
|
</ul>
|
|
|
|
<p>
|
|
By "support", we mean "make useable 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. But we can't predict
|
|
which services will be necessary down the road, so we'll continually
|
|
monitor formats and techniques to ensure we can accomodate needs
|
|
as they arise.
|
|
</p>
|
|
|
|
<p>
|
|
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
|
|
<!-- FIXME: Make a link! <a href="submit_guide.html#info">-->
|
|
DSpace Format Reference Collection<!-- FIXME </a>-->.
|
|
Unfortunately, this
|
|
means that proprietary formats for which these materials are not
|
|
publicly available cannot be supported in DSpace. We will still
|
|
preserve these files, and in cases where those formats are
|
|
native to tools supported, we will
|
|
provide you with guidance on converting your files into formats
|
|
we do support. It is also likely that for extremely popular but
|
|
proprietary formats (such as Microsoft .doc, .xls, and .ppt),
|
|
we will be able to help make files in those
|
|
formats more useful in the future simply because their
|
|
prevalence makes it likely tools will be available. Even so, we
|
|
cannot guarantee this level of service without also having more
|
|
information about the formats, so we will still list these
|
|
formats as "known", not "supported".

The table below lists the DSpace default level of support for various format types. Please note
|
|
your local DSpace installation may have a different level of support for the formats listed. If you
|
|
have any questions about support levels, you should contact your
|
|
<a href="#" onClick="javascript:window.open('../components/contact-info.jsp', 'contact', 'location=no,menubar=no,height=300,width=550,resizable')">DSpace Administrator</a>.</p>

|
<p>In the table below, <b>MIME type</b> is the Multipurpose Internet Mail
|
|
Extensions (MIME) type identifier; for more
|
|
information on MIME, see the <a href="http://www.nacs.uci.edu/indiv/ehood/MIME/MIME.html">MIME RFCs</a> or the <a href="http://www.faqs.org/faqs/mail/mime-faq/">MIME FAQ</a>.
|
|
<b>Description</b> is what most people use as the name for the format.
|
|
<b>Extensions</b> 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 DSpace, so either "sample.XML" or "sample.xml" will
|
|
be recognized as XML.
|
|
<b>Level</b> is DSpace's support level for each format:
