Analysis and Summary of Feasible Marketplace Business Models Covering All Trials

This report analyses the market for cloud services of the type that POSTMARK is pioneering including type, scale, readiness and barriers to adoption. The POSTMARK trials are reviewed in terms of the business benefits that the services offer, the validation of these by those involved in the trials, and the further work needed to move from trials to a fully commercial and production setting. Business benefits were wide ranging and included lowering costs, better meeting of deadlines, increase in volume of business, and improved customer service. Response from the trials was positive in all cases. This was echoed by the two public demonstration events hosted by the project in 2012 where the attendees (around 100 in total from the film and post communities) were positive about the services that POSTMARK is offering. The main barriers encountered were security, the need for high levels of availability and trust, the need for complete out-of-the box solutions, and of course concerns over cost. These mirror findings in industry surveys and analyst reports. These barriers are not insurmountable but do require further investment to address. The key question is whether the market as a whole is sufficiently aware of, and ready to adopt, new services of the type developed by POSTMARK.Indications are good, but large scale adoption would be necessary to give sufficient return on the investmentneeded to provide fully operational POSTMARK services on a supported and commercial basis

Audiovisual preservation strategies, data models and value-chains

This is a report on preservation strategies, models and value-chains for digital file-based audiovisual content. The report includes: (a)current and emerging value-chains and business-models for audiovisual preservation;(b) a comparison of preservation strategies for audiovisual content including their strengths and weaknesses, and(c) a review of current preservation metadata models, and requirements for extension to support audiovisual files

Tools for modelling and simulating migration-based preservation

This report describes two tools for modelling and simulating the costs and risks of using IT storage systems for the long-term archiving of file-based AV assets. The tools include a model of storage costs, the ingest and access of files, the possibility of data corruption and loss from a range of mechanisms, and the impact of having limited resources with which to fulfill access requests and preservation actions. Applications include archive planning, development of a technology strategy, cost estimation for business planning, operational decision support, staff training and generally promoting awareness of the issues and challenges archives face in digital preservation

Storage and Services: Planning and managing cost, quality and risk

PrestoPRIME (www.prestoprime.eu) is a European project that has launched the PrestoCentre, and has also developed a range of tools for digital audiovisual content: collections moving from tapes-on-shelves to files-on-mass-storage. This presentation focusses on planning and cost models for mass storag

Digital preservation strategies for AV content

The mass digitisation of analogue archive holdings plus the transition to tapeless production for new content means AV archives inevitably face the prospect of file-based archiving solutions using IT storage technology. But what is the long-term Total Cost of Ownership (TCO) of these systems, which file formats should be used, what storage technologies make sense, what are the risks involved, what is the additional cost of managing these risks, and what new software approaches can be applied? These are all issues being explored by major broadcasters, national archives and technology specialists in the European PrestoPrime project and the UK AVATAR-m project

Semantic Web Integration of Cultural Heritage Sources

In this paper, we describe research into the use of ontologies to integrate access to cultural heritage and photographic archives. The use of the CIDOC CRM and CRM Core ontologies are described together with the metadata mapping methodology. A system integrating data from four content providers will be demonstrated

eCHASE: Exploiting Cultural Heritage using the Semantic Web

The eCHASE project is using semantic web technologies to demonstrate sustainable business models based on access and exploitation of digital cultural heritage content at a European level. In this paper we describe the eCHASE project and outline the system architecture

eCHASE: Sustainable Exploitation of Electronic Cultural Heritage

Europe’s digital cultural heritage content has tremendous exploitation potential in applications such as Education, Publishing, e-Commerce, Public Access and Tourism. Value is hugely amplified if the content can be aggregated, repurposed and distributed at a European level. The eCHASE project seeks to demonstrate that public-private partnerships between content holders and commercial service providers can create new services and a sustainable business based on access and exploitation of digital cultural heritage content. This paper describes these issues and introduces the eCHASE architecture that is being developed to showcase the business models created for the project

An Integrated Content and Metadata based Retrieval System for Art

In this paper we describe aspects of the Artiste project to develop a distributed content and metadata based analysis, retrieval and navigation system for a number of major European Museums. In particular, after a brief overview of the complete system, we describe the design and evaluation of some of the image analysis algorithms developed to meet the specific requirements of the users from the museums. These include a method for retrievals based on sub images, retrievals based on very low quality images and retrieval using craquelure type

Effects of zinc and vitamin A supplementation on prognostic markers and treatment outcomes of adults with pulmonary tuberculosis: a systematic review and meta-analysis

Introduction: Undernutrition is a major risk factor for tuberculosis (TB), which is estimated to be responsible for 1.9 million TB cases per year globally. The effectiveness of micronutrient supplementation on TB treatment outcomes and its prognostic markers (sputum conversion, serum zinc, retinol and haemoglobin levels) has been poorly understood. This study aimed to determine the effect of zinc and vitamin A supplementation on prognostic markers and TB treatment outcomes among adults with sputum-positive pulmonary TB. Methods: A systematic literature search for randomised controlled trials (RCTs) was performed in PubMed, Embase and Scopus databases. Meta-analysis with a random effect model was performed to estimate risk ratio (RR) and mean difference (MD), with a 95% CI, for dichotomous and continuous outcomes, respectively. Results: Our search identified 2195 records. Of these, nine RCTs consisting of 1375 participants were included in the final analyses. Among adults with pulmonary TB, zinc (RR: 0.94, 95% CI: 0.86 to 1.03), vitamin A (RR: 0.90, 95% CI: 0.80 to 1.01) and combined zinc and vitamin A (RR: 0.98, 95% CI: 0.89 to 1.08) supplementation were not significantly associated with TB treatment success. Combined zinc and vitamin A supplementation was significantly associated with increased sputum smear conversion at 2 months (RR: 1.16, 95% CI: 1.03 to 1.32), serum zinc levels at 2 months (MD: 0.86 μmol/L, 95% CI: 0.14 to 1.57), serum retinol levels at 2 months (MD: 0.06 μmol/L, 95% CI: 0.04 to 0.08) and 6 months (MD: 0.12 μmol/L, 95% CI: 0.10 to 0.14) and serum haemoglobin level at 6 months (MD: 0.29 μg/dL, 95% CI: 0.08 to 0.51), among adults with pulmonary TB. Conclusions: Providing zinc and vitamin A supplementation to adults with sputum-positive pulmonary TB during treatment may increase early sputum smear conversion, serum zinc, retinol and haemoglobin levels. However, the use of zinc, vitamin A or both was not associated with TB treatment success
