  1. Aggregating E-Journals: Adopting the Journal Archiving and Interchange Tag Set to Build a Shared E-Journal Archive for Ontario Wei Zhao & vidhya Arvind November 1, 2010

  2. OCUL Scholars Portal Services • OCUL is a consortium of twenty-one university libraries in the province of Ontario • Scholars Portal is a project of OCUL to provide shared technology infrastructure and shared collections to OUCUL universities • Scholars Portal services includes digital content of ebooks, ejournals, statistics data, interlibrary loan and reference management

  3. SP E-Journals--Introduction • digital repository containing 20,000,000 articles from over 8900 full text journals of 18 publishers which covers every academic discipline • The materials loaded in Scholars Portal E-journals archive include journal articles and conference proceedings with ISSNs. According to the agreement with the publishers, the metadata, cited reference, full-text, and supplementary materials are transformed to NLM DTD XML when they are available.

  4. Adopting NLM DTD--Background • The publisher’s data is in different format using different DTD/Schema • Publisher’s data need to be normalized to a single standard for archiving, display and searching • NLM DTD was chose based on the features it can offer

  5. The practice of Adopting NLMDTD—Work flow • Two steps—mapping and coding • Mapping—created by metadata librarian in spread sheet • Coding—done by the programmer using coding languages such as Java and Perl

  6. The practice of Adopting NLMDTD—NLM DTD customization • A set of <custom> elements was added for loading information • Attribute “display” in <body> tag • pdf-size in <custom-meta> tag • “non-latin” attribute was added • The use of <elocation-id> and <object-id> for citation linking

  7. Journal TOC structure • Although the primary intellectual value of e-journals rests at the item-level, the issue level structure is the key to navigate around the journal issues. NLM DTD defined item-level, so the issue level structure was created by our own. All the issue level textual content is encoded in a single xml

  8. The practice of Adopting NLMDTD—Additional tagging rules and policies • local rules applied on how certain tags should be used and how certain documents should be tagged • All the documentation is posted in wiki to share within team members.

  9. Challenges of adopting the Tag Set • Decisions need to be made when there are multiple options for transforming the publishers’ tag and these decisions need to be followed consistently to support normalized searching. • The normalization is not straightforward even the source data is in NLM DTD family. • Moving all our content to version 3.0 of the tag set?
