-====== Open Archives (OAI), Open Access (OA) and Open Data Sources ======
+====== Open Data Sources ======
-This page is designed to list Open Archives that provide metadata mostly from Open Access repositories, journals, databases or other services that provide access to the full-text of their contents, and Open Data sources that might be useful to add to a VuFind instance.  Feel free to add new sources as you find them.
+There is a great deal of freely-available data which may be useful to add to your local VuFind® instance. Authority records from large organizations and standards bodies can help augment your index with cross-references, and Open Access publications can expand the collection that you present to your users.
+This page links to a variety of open resources that you might find useful, most of which can be harvested and ingested using standard VuFind® tools. Feel free to add new sources as you find them.
 ===== Authority Data =====
-==== OCLC FAST ====
+  * [[indexing:open_data_sources:fast|OCLC FAST]] - free, general purpose authority data for names, subjects and more
+  * [[indexing:open_data_sources:mesh|MeSH]] - medical subject headings
-You can download OCLC's subject authority records in MARC-XML format (easy to import into VuFind's authority module) [[https://www.oclc.org/research/areas/data-science/fast/download.html|here]].  Note that you will need to rename the files from *.marcxml to *.xml in order for SolrMarc to recognize the file format correctly. Once you have done this, make sure that you have the FAST properties import configurations in your import directory (//if you have a version of VuFind earlier than 1.4, you can download the necessary files [[https://vufind.svn.sourceforge.net/svnroot/vufind/trunk/import/|here]] -- all filenames begin with "marc_auth_fast"//).
-From your VuFind directory you can then import each file as follows:
-<code>
-./import-marc-auth.sh [.xml filename] [properties file for that FAST dataset]
-</code>
-Both the XML filename //and// the corresponding properties filename are required!
-Note: replace "./import-marc-auth.sh" with "import-marc-auth.bat" when using Windows.
-==== 2012 MeSH/MARC21 ====
-U.S. National Library of Medicine authority records (MeSH), MARC21 format, 2012 version are available to download upon completion of an online memorandum of understanding (easy and fast to import into VuFind's authority module): [[http://www.nlm.nih.gov/mesh/marc.html|here]] -- look for the link "Download full file [153MB]".
-A conversion from .bin (ISO2709) into .mrc is required, easily done with Terry Reese's [[http://people.oregonstate.edu/~reeset/marcedit/html/downloads.html|MarcEdit]]; use MARC Tools > Function: MarcBreaker and then in MARC Editor > "Compile File into MARC".
-A local marc_mesh.properties has to be built in order to map correctly the authority fields used in MeSH (refer to marc_auth.properties as an example).
-The following fields should do the work:
-<code>
-id = script(getFirstNormalizedLCCN.bsh), getFirstNormalizedLCCN("001")
-source = "U.S. National Library of Medicine authority records (MeSH)"
-heading = 100abcdegjqt:110abcdegjqt:111abcdegjqt:130abcdegjqt:150abvxyz:151a:155avxyz:180vxyz:181vxyz:182vxyz:185vxyz
-use_for = 400abcdegjqt:410abcdegjqt:411abcdegjqt:430abcdegjqt:450abvxyz:451a:455avxyz:480vxyz:481vxyz:482vxyz:485vxyz
-see_also = 500abcdegjqt:510abcdegjqt:511abcdegjqt:530abcdegjqt:550abvxyz:551a:555avxyz:580vxyz:581vxyz:582vxyz:585vxyz
-scope_note = custom, getAllSubfields(667:680:688, " ")
-</code>
-According to NLM, this “full file contains all terms with 26,581 descriptor records, 83 qualifier records, and 593,280 descriptor/qualifier combinations, for a total of 619,944 records”.
 ===== Bibliographic Data =====
-==== PubMed Central OAI service (PMC-OAI) ====
+  * [[indexing:open_data_sources:doaj|Directory of Open Access Journals (DOAJ)]]
+  * [[indexing:open_data_sources:intech|InTech Open]] - metadata about open access eBooks in the fields of Science, Technology and Medicine
-"(...) provides access to metadata of all items in the PubMed Central (PMC) archive, as well as to the full text of a subset of these items"; full info [[http://www.ncbi.nlm.nih.gov/pmc/tools/oai/|here]].
+  * [[indexing:open_data_sources:ndltd|Networked Digital Library of Theses and Dissertations (NDLTD)]]
+  * [[indexing:open_data_sources:pubmed_central|PubMed Central OAI Service]] - metadata from the PubMed Central archive
-Suggested entry in ./harvest/oai.ini:
-<code>
-[pubmed]
-url = http://www.pubmedcentral.nih.gov/oai/oai.cgi
-;set = "pmc-open"
-metadataPrefix = oai_dc
-idSearch[] = "/^oai:pubmedcentral.nih.gov:/"
-idReplace[] = "pubmed-"
-idSearch[] = "/\//"
-idReplace[] = "-"
-injectId = "identifier"
-injectDate = "datestamp"
-</code>
-Change "metadataPrefix" entry accordingly to the desired format (mostly because of the level of information provided you might want: oai_dc = basic level, but more easy to parse (XSLT); pmc or pmc_fm = higher level [more metadata], but also more complex to parse).
-==== NDLTD: Networked Digital Library of Theses and Dissertations ====
-"Networked Digital Library of Theses and Dissertations (NDLTD), an international organization dedicated to promoting the adoption, creation, use, dissemination, and preservation of electronic theses and dissertations (ETDs)"
-Suggested entry in ./harvest/oai.ini:
-<code>
-url = http://union.ndltd.org/OAI-PMH/
-metadataPrefix = oai_dc
-idSearch[] = "/^oai:union.ndltd.org:/"
-idReplace[] = "NDLTD-"
-idSearch[] = "/\//"
-idReplace[] = "-"
-idSearch[] = "/:/"
-idReplace[] = "-"
-injectId = "identifier"
-injectDate = "datestamp"
-</code>
-To import records into your VuFind installation just do a svn checkout of the two necessary files (from VuFind trunk):
-https://vufind.svn.sourceforge.net/svnroot/vufind/trunk/import/ndltd.properties
-https://vufind.svn.sourceforge.net/svnroot/vufind/trunk/import/xsl/ndltd.xsl
-and perform any desired adjustment.
-For a deeper understanding of the XSL Transformation done in ndltd.xsl, please refer to VuFind JIRA tickets:
-http://vufind.org/jira/browse/VUFIND-501 | http://vufind.org/jira/browse/VUFIND-493                     http://vufind.org/jira/browse/VUFIND-499
-==== DOAJ - Directory of Open Access Journals: Articles ====
-Most people are not aware that DOAJ not only provide a Directory of OA journals, but also harvest their articles, which in turn are available to be harvested from DOAJ. And better news, yet: in oai_doaj metadata format (very similar to NLM's -- much richer than standard oai:dc). This allows something like
-  Journal Title: BMGN Low Countries Historical Review    vol: 85    issue: 1
-With the first field value (container_title) searchable – to obtain all the articles from this Journal, and the other two acting as filters over this Journal (filter to retrieve all the articles published in the 85th volume or from the first issue in this volume).
-Please be aware that you have also the possibility of just harvest the journal relation themselves indexed in DOAJ (will not retrieve their articles, but rather, Journals’ info).
-Suggested entry in ./harvest/oai.ini:
-<code>
-[DOAJart]
-url = https://doaj.org/oai.article
-metadataPrefix = oai_doaj
-idSearch[] = "/oai:doaj.org\/article:/"
-idReplace[] = "doaj-art-"
-injectId = "identifier"
-injectDate = "datestamp"
-</code>
-There is format definition ready for VuFind harvester (see files ./import/doaj.properties and ./import/xsl/doaj.xsl).
-This service was first discussed in the [[http://vufind.org/jira/browse/VUFIND-543|VUFIND-543]] JIRA ticket.
-:!: The DOAJ format changed significantly between VuFind versions 3 and 4. If your harvest is not working, you may need to update your XSLT. See pull request [[https://github.com/vufind-org/vufind/pull/944|#944]] for details.
-:!: If you are using a VuFind version less than 4.0 or a VuFindHarvest version less than 2.3.0, there is a bug that will affect the harvested xml files, and you probably will need to adjust them; this command could help:
-<code>
-sed -i "s/xmlns:oai_doaj/ xmlns:oai_doaj/" local/harvest/DOAJart/*.xml
-</code>
-==== InTech Open (e-Books) ====
-"InTech is a pioneer and world's largest multidisciplinary open access publisher of books covering the fields of Science, Technology and Medicine. Since 2004, InTech has collaborated with more than 70 000 authors and published 1827 books and 12 journals with the aim of providing free online access to high-quality research and helping leading academics to make their work visible and accessible to diverse new audiences around the world."; full info [[http://www.intechopen.com/about-intech.html|here]].
-Suggested entry in ./harvest/oai.ini:
-<code>
-[InTech]
-url =  http://www.intechopen.com/oai/
-metadataPrefix = oai_dc
-idSearch[] = "/oai:intechopen.com:/"
-idReplace[] = "InTech-"
-injectId = "identifier"
-injectDate = "datestamp"
-</code>
-Suggested InTech.properties:
-<code>
-; XSLT Import Settings for InTech Open (e-Books) OAI XML files
-[General]
-; REQUIRED: Name of XSLT file to apply.  Path is relative to the import/xsl directory
-; of the VuFind installation.
-xslt = InTech.xsl
-; OPTIONAL: PHP function(s) to register for use within XSLT file.  You may repeat
-; this line to register multiple PHP functions.
-php_function[] = utf8_encode
-; OPTIONAL: PHP class filled with public static functions for use by the XSLT file.
-; The class name must match the filename, and the file must exist in the import/xsl
-; directory of the VuFind installation.  You may repeat this line to load multiple
-; custom classes.
-custom_class[] = VuFind
-; XSLT parameters -- any key/value pairs set here will be passed as parameters to
-; the XSLT file, allowing local values to be set without modifying XSLT code.
-[Parameters]
-institution = "My University"
-collection = "e-books"
-building = ""
-</code>
-Full exploit of data provided: InTech.xsl
-!! Warning: contains some "hacks" to have direct access to the PDF of the entire e-book, distinguish Book Chapters e-books from journal articles (<dc:relation>ISBN:0</dc:relation> and other vars), etc.. -- use at your own risk as they are by no means endorsed or supported in any way by InTech !!

-Note: this .xsl invokes a new function "VuFind::InverteNome". This means that a new function "InverteNome" (Portuguese for Inverts (the author) Name), that builds an inverted form of the Author's name when it detects that it is in a non-inverted form, must be added to ./import/xsl/vufind.php (for your convenience all the code comments were translated from Portuguese to English :) ):
-<code>

-===== Shared Index =====
-There has been some discussion about building a shared VuFind index of open content.  This is an ambitious project that is currently just in the idea stage.  Feel free to comment on the [[http://vufind.org/jira/browse/VUFIND-570|JIRA ticket]] if you have thoughts on the subject.
-===== Further sources of common interest =====
-A special request: please state which sources you know of (that implement OIA-PMH, that have records that can be bulk downloaded or websites that have a sitemap.xml -- although others should be possible to be added, crawling them and generating a sitemap.xml via specific software or services like http://www.xml-sitemaps.com) and would like to be analyzed and possible XSLT files generated to import their records into VuFind.
-Please refer them (including their info URL, if possible), as a comment in the dedicated [[http://vufind.org/jira/browse/VUFIND-570|JIRA ticket]], mentioned above. Thanks!
-====== Related projects, possible sources of data ======
-Bibliographic and/or usage|circulation data
-===== LOBID: Linking Open Bibliographic Data =====
-[[http://lobid.org|This service]], courtesy of the North Rhine-Westphalian Library Service Center, provides shareable bibliographic data in linked-data format.  As if this writing, VuFind does not include tools to ingest this data, but it may be worth investigating in the future.
-===== LibraryCloud =====
-"LibraryCloud is an open, multi-library data service that aggregates and delivers library metadata. We hope it will serve as a platform for the development of Web applications that help all library users (including scholars and re-searchers) find and understand materials."
-"(LibraryCloud) It's a metadata server. It gathers up metadata - information about information - from libraries, museums, and other participating institutions, and makes that metadata available to any application that wants to use it."
-... more info [[http://www.librarycloud.org/|here]].
-===== SPLURGE: Scholars Portal Library Usage-Based Recommendation Generation Engine =====
-"Amazon.ca has a "customers who bought this item also bought" feature that recommends things to you that you might be interested in. LibraryThing has it too: the recommendations for What's Bred in the Bone by Robertson Davies include books by Margaret Laurence, Carol Shields, Michael Ondaatje, Peter Ackroyd, John Fowles, and David Lodge, as well as other Davies works.
-Library catalogues don't have any such feature, but they should. And libraries are sitting on the circulation and usage data that makes it possible. (BiblioCommons does have a Similar Titles feature, but it's a closed commercial product aimed at public libraries, and anyway the titles are added by hand.)

-====== Linked Data, Linked Open Data (LOD) ======
-Linked Open Data (LOD), that may be considered as part of the [[http://en.wikipedia.org/wiki/Open_data|Open Data]] Movement (which aims at making data freely available to everyone) and could be described as a "recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF" ([[http://linkeddata.org/|source]]), has recently gained prominence in many (Digital) Libraries and Archives events and related discussions.
-The recent [[http://vustuff.org/vustuff/tech-trifecta|Tech Trifecta]] series of conferences' (that took place at Villanova University's Falvey Memorial Library, home of VuFind) presentations and discussions, namely at [[http://vufind.org/wiki/vufind_summit_2012|VuFind Summit 2012]], were a major example that LOD is currently a hot issue and gathers the interest of many institutions. This section presents some selected LOD resources (information, presentations, etc.). Please feel free to add or correct the entries as needed.

-===== Sharing and Aggregating Social Metadata =====
-A pragmatic usage of LOD within VuFind would be using it as a feasible, light weight alternative to have a shared/common index of open content (mentioned [[http://vufind.org/wiki/open_data_sources#shared_index|above]] / please refer to [[http://vufind.org/jira/browse/VUFIND-570|VUFIND-570]] JIRA ticket).
-By implementing mechanisms for exposing and harvesting social metadata, VuFind installations would be able not only to share their own UGC (User Generated Content / social metadata) but also to collect social metadata from specific VuFind installations. Please refer to [[http://vufind.org/wiki/developers_call:minutes20121113#linked_data|2012-11-13 developers call’ minutes]] for some initial thoughts about this approach.
