Enriching Library Metadata with APIs
Mak, Lucas
Given the ever-dwindling resources assigned to metadata creation, individual libraries are hard-pressed to create and maintain high quality traditional metadata across-the-board, let alone to prepare and transform legacy data into linked data. Coming up with no additional support by looking inside, one should look outside for resources that can help mitigate the situation. Nowadays, libraries no longer monopolize metadata creation. More and more special domain communities have set up Wikipedia-like crowd-sourced portals to serve information needs of their members. At the same time, there are international initiatives in the library community to set up data stores for linked data sets. Can the library tap into these rich information resources, in an efficient way, to enrich library metadata in the traditional way as well as prepare the legacy data for the big migration? This presentation will discuss how Michigan State University Libraries is able to harvest selected metadata from various library and non-library community based portals through APIs (Application Programming Interface) in a batch and automated fashion to enrich existing metadata of a popular music collection and enhance them with URIs for linked data conversion down the road.

From XML to MARC: RDF Behind the Scenes
Nicolas, Yann
We collect heterogeneous metadata packages from various publishers. Although all of them are in XML, they vary a lot in terms of vocabulary, structure, granularity, precision, and accuracy. It is quite a challenge to cope with this jungle and recycling it to meet the needs of the Sudoc, the French academic union cataloguing system. How to integrate and enrich these metadata? How to integrate them in order to process them in a regular way, not through ad hoc processes? How to integrate them with specific or generic controlled vocabularies ? How to enrich them with author identifiers, for instance? RDF looks like the ideal solution for integration and enrichment. Metadata are stored in the Virtuoso RDF database and processed through a workflow steered by the Oracle DB. We will illustrate this generic solution with Oxford UP metadata: ONIX records for printed books and KBART package description for ebooks. So. A relational database as glue and pipeline engine… RDF as internal model… MARC as output …. Quite weird… Was this abstract written by an ELAG-specific random text generator?

Metadata integration in data warehouse
Volf, Karel ; Matějka, Martin (advisor) ; Novotný, Ota (referee)
This diploma thesis aim at the implementation of metadata in the context of data warehouses and Business Intelligence. Metadata can provide significant benefits to the organization, help address regulatory requirements, and increase the use of BI tools to prevent user denial. The main goals of the diploma thesis are the metadata integration according to the theoretical knowledge from the first part of this thesis and the practical implementation of the solution of consolidating business and technical metadata in the second part of the thesis. The first chapter defines the goals of the work and the expected benefits. The second chapter defines the concept of metadata, types and standards. Chapter three provide metadata context in the perspective of company's data governance, and summarize an analytical market for metadata and data integration tools. The fourth chapter evaluates the usability of metadata based on research on the subject. The fifth chapter describes one of the possible metadata integration solutions according to the theoretical knowledge summarized in the preceding chapters. The sixth chapter summarizes the practical experience of implementing the solution into the insurance company BI environment. The main contribution of the thesis is the description of implementation of the real solution and its evaluation.

Processing image metadata in XSLT/XQuery
Šubrt, Matěj ; Kosek, Jiří (advisor) ; Vojíř, Stanislav (referee)
This bachelor thesis deals with how to obtain information from image formats, especially those that use Exif specification for storing metadata, which offers a lot of information about the image. The work focuses on creating a library that gets these meta-data from the image using XSLT, XQuery and XPath. A simple application/transformation is also part of the work, which can extract the metadata from the enclosed images and display them to the user.
