abstract = {Advances in the publishing world have emerged new models of digital library development. Open access publishing modes are expanding their presence and realize the digital library idea in various means. While user-centered evaluation of digital libraries has drawn considerable attention during the last years, these systems are currently viewed from the publishing, economic and scientometric perspectives. The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive. The results demonstrate that several attributes of usefulness, such as the level and the relevance of information, and usability, such as easiness of use and learnability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction.

abstract = {Museum collections are characterized by heterogeneity, since they usually host a plethora of objects of categories, while each of them requires different description policies and metadata standards. Moreover the museum records, which keep the history and evolution of the hosted collections, request proactive curation in order to preserve this rich and diverse information. In this paper, the architecture of an innovative museum information system, as well as its implementation details is presented. In particular the requirements and the system architecture are presented along with the problems that were encountered. The main directions of the system design are (a) to increase interoperability levels and therefore assist proactive curation and (b) to enhance navigation by the usage of handheld devices. The first direction is satisfied by the design of a rich metadata schema based on the CIDOC/CRM standard. The second direction is fulfilled by the implementation of a module, which integrates the museum database with a subsystem appropriate to support user navigation into the museum floors and rooms. The module is expressed as a navigation functionality, which is accessed through handheld devices and peripherals, such as PDAs and RFID tags. The proposed system is functional and operates into the Solomos Museum, situated in Zakynthos island, Greece.},

abstract = {This paper is motivated by the demand for unified access, navigation and information
retrieval from the wealth of composite, distributed and heterogeneous digital cultural
collections. The last years, collection-level metadata is considered to be the key of
integrated access of so many resources, since they represent the inherent and contextual
characteristics of a collection. Our effort origins from the semantic interoperability
perspective and considers CIDOC/CRM as the mediating schema, which integrates in
an optimal way the semantics of the collection level metadata schemas and application
profiles. In particular a crosswalk between Dublin Core Collections Application Profile
and CIDOC/CRM is presented so that the semantics of each DCCAP element is mapped
to CIDOC/CRM. The derived crosswalk is bidirectional implementing the mapping
from DCCAP to CIDOC/CRM and vice versa. The paper reveals the complexity of
mapping metadata schemas to ontologies and resolves particular difficulties providing a
real world semantic integration case. },
