  4. Thai capital braces for flood disaster October 11, 2011|By Paul Armstrong, CNN On Monday, Thai Prime Minister YingluckShinawatra ordered canal dredging and reinforcement of flood-prevention embankments to protect the city, state-run news agency MCOT reported. In addition, three new flood-prevention walls were being built at two locations in Rangsit, in northern Bangkok, and in Taling Chan, in the western part of the city. Tourists warned as floods continue to wreak havoc in Thailand The government needs another 1.5 million sandbags, MCOT reported. The prime minister called on the private sector to supply them, but said the government will buy all the needed sandbags by Wednesday, the news agency said. Meanwhile, around 1,200 people have taken shelter in a gymnasium at Bangkok's Thammasat University. Most of them are from neighboring Ayutthaya province and other flood-affected areas around the capital, said ThanawatSrisuwan, a volunteer at the makeshift shelter. The authorities have set up almost 200 other temporary shelters around the city to receive flood victims. The Bangkok Metropolitan Administration said plans were in place to evacuate people from nine areas, mainly in eastern Bangkok, if needed. Elsewhere, patients in two hospitals in Thailand's Ayutthaya and NakhonSawan provinces had to be evacuated after water reached the first floor, the flood operations command said. Multiple tropical weather systems have moved over the region in recent weeks, enhancing monsoon rains and leading to the flooding. Another low pressure system is forecast to move into Southeast Asia on Tuesday and Wednesday, said Brandon Miller, senior meteorologist for CNN International. According to the government website Thaiflood.com, water from northern Thailand has finally reached lower parts of central Thailand, penetrating dykes in Pathumthani and Nonthaburi provinces and flooding outer areas of Bangkok, including the market in Nonthaburi and Chiang Rang road. Elsewhere, patients in two hospitals in Thailand's Ayutthaya and NakhonSawan provinces had to be evacuated after water reached the first floor, the flood operations command said. http://articles.cnn.com/2011-10-11/world/world_thailand-floods_1_flood-prevention-flood-victims-monsoon-rains?_s=PM:WORLD

  28. Criteria • Durability of interpretation over the time • Durability of interpretation across designated communities • Interoperability of linked digital archives • Interoperability of linked concepts and contextual knowledge Chowdhury, G. (2010). From digital libraries to digital preservation research: the importance of users and context. Journal of Documentation, 207 - 223.

  29. Europeana Description • Portal for million digital resources for many museums Information Model • Offers standard schema • Linked digital with difference schema • Works across the cultural heritage divide. • Multi-lingual Explore Europe's cultural collections

  30. SHAMAN Description • Preserve context by linking relevant resources with in the document process Information Model • Preserve resources with work-result, event, agent, and comment • Linked relevant resources from document process-centric perspective • Multi-lingual Sustaining Heritage Access through Multivalent ArchiviNg

  31. CASPAR Description • Preserve, access, and understand digital resource Information Model • Gap Manager • Organize knowledge structure • Manage designated community • Identification of the data objects that are in danger in case a module (e.g. software or format) is becoming obsolete • Understand source code requires knowledge about programming Cultural, Artistic and Scientific knowledge for Preservation, Access and Retrieval

  32. Comparison A Logical Model for Digital Archive Europeana SHAMAN CASPAR Durability of interpretation over the time Durability of interpretation across designated communities Interoperability of linked digital archives Interoperability of linked concepts and contextual knowledge

  33. Future Works To enhance the model with evolution of ontology To improve user experience for the digital archive system
