Building a digital library of antique documents involves not only technical implementation issues, but also aspects related to the digitization of large collections of documents. Antique documents are usually delicate and need to be handled with care. Also, a poor state of preservation and the use of unrecognizable font types make automatic text recognition more difficult, hence requiring a further human revision to perform text corrections. This makes the participation of experts in the digitization process mandatory and, therefore, costly. In this paper, we present a framework for managing the workflow of the digitization of large collections of antique documents. We describe the digitization process, and a tool supporting all of its phases and tasks. We also present a case study in which we describe how the workflow management system was applied to the digitization of more than 10,000 documents from journals of the 19th century. In addition, we describe the resulting digital library, focusing on the most important technological issues.

“…The work done in [5] explores the integration of transactional features and Workflow Management Systems (WfMS) to support workflow recovery at runtime. Some approaches exist [6,13] that consider workflow recovery at design time based on the concept of exception handling. For example, in [6] the authors focus on the combination of exception handling mechanisms and the transaction concept used in databases to support the design and implementation of reliable workflow processes.…”

Abstract. This paper describes an approach for reasoning about the repairability of workflows at design time. We propose a heuristic-based analysis of a workflow that aims at evaluating its definition, considering different design aspects and characteristics that affect its repairability (called repairability factors), in order to determine if the workflow schema supports repairable executions of its activities through the application of repair actions. The analysis intents to identify and evaluate the impact of critical design flaws affecting the repairability of workflows. The results of this analysis are fed back to the workflow designer and used to improve the repairability of the workflow by making appropriate changes to its definition.

Abstract. Exception handling is a fundamental functionality of workflow management systems (WfMS). User involvement in exception handling is recognized as critical in various situations due to the unpredictability nature of the exceptions that can occur in a running workflow (WF) engine. The problem however is how to orchestrate human ad hoc interventions with a minimum impact on system integrity. The control flow and data integrity dimensions of the impact are analyzed. Our perspective is to allow the maximum latitude possible to user interventions while keeping system correctness. We propose a solution that uses a WF to guide users handling WF exceptions. Furthermore, we extended the WF engine with a propagation mechanism allowing users to involve multiple members of the organization in the exception handling WF. This solution is implemented in the OpenSymphony (OS) platform. The implementation details of the proposed solution in the OS platform are also given in the paper.
