102 Personal Content Experience: Managing Digital Life in the Mobile Age with any text editor. In addition to the transfer format itself, MARC also requires cataloguing rules that defi ne the semantics of various fi elds. MARC was defi ned in 1960s, and is well-established with thor- oughly thought-out rules and semantics that have evolved over centu- ries along with library cataloguing. Furthermore, since the format is extensible, and the semantics are not tied with the syntax, it is easy to expand when needed, and is usable across several different types of multimedia objects, not just books. From the viewpoint of personal content, MARC feels like overkill – or not enough. Most people are not interested in classifying their content with scholarly accuracy. Instead, they want to focus on the enjoyment, experiences, and emotion. While MARC pioneered many of the concepts that newer formats use, it does not seem to raise enough interest for the mobile content domain. Or, it may just be that librarians do not speak with people on the Internet and computing domain – and vice versa. 4.6.2 Dublin Core Metadata Initiative One of the most important efforts for creating a standard for general 28 resource description is Dublin Core Metadata Initiative (DCMI). As stated in its home page: The Dublin Core Metadata Initiative (DCMI) is an organization dedicated to promoting the widespread adoption of interoperable metadata standards and developing specialized metadata vocabularies for describing resources that enable more intelligent information discovery systems. The mission of DCMI is to provide simple standards to facilitate fi nding, sharing, and management of information by the means of developing and maintaining international standards for describing resources, supporting a worldwide community of users and developers, 29 and promoting widespread use of Dublin Core solutions. This is an ambitious goal, considering all potential information sources and back- grounds of the content creators, users, and distributors with a variety of needs and expectations. DCMI is not a metadata standard as such, but instead aims to main- 30 tain a core set of metadata terms. The metadata terms, then, include 28 http://dublincore.org/ 29 General description of Dublin Core: http://dublincore.org/about/ 30 DCMI Terms: http://dublincore.org/documents/dcmi-terms/
