1 A Case Study of Assembly Media Archive Aided Publishing Grip Studios Interactive, Aki Kivelä

2 Assembly 04 Media Archive WWW publishing platform. Publishes images, videos and related metadata real-time. Integrated to Assembly s [1] publishing environment. Uses s [2] to store knowledge. Supports heterogeneous data sources. Short development time. Short life span. [1] Assembly 04 [2] Steve Pepper. The TAO of s, finding the way in the age of infoglut 2

8 Merge Problem Merged How to distinguish which properties of merged (yellow) topic came from blue topic map? Merge looses information and partial merge is not possible! 8

9 Concept of Virtual In virtual merged topics are wrapped into a container (virtual topic). Merged Virtual Topic properties are solved run-time by container. Partial merge is possible because merged topics remain! 9

10 Reduced Implementation Many of the standard [5] features of s had little use in Assembly Media Archive. For example Multiple base names Resource reference occurrence Multiple scopes for occurrences Association scopes Getting rid of these features enabled the topic map implementation to be faster and more memory efficient. [5] ISO/IEC 13250:

14 The Good, The Bad and The Questions Conclusion Good Transformations: XML XTM HTML Merging s Intuitive navigation structure of Search engine powered navigation Bad implementations inefficient Introducing reduced implementation! Merging s Introducing concept of virtual Redundant features of standard Reduced implementation of s Questions Where is the semantic or intelligence hiding? Is just another data storage format? 14
