Next week is the annual Archiving conference in Berlin. Last year we presented our service architecture and open source development model in Archiving 2013 in Washington DC. Now that the project has progressed, we can publish concrete results and deliverables.
I will be presenting two papers. Both papers will be published in the IS&T’s annual Archiving publication. And of course, will be available on request from us. The first paper is Flexible data model for linked objects in digital archives by Mikko Lampi (that’s me) and Olli Alm (Information services and development manager at Central Archives for Finnish Business Records). In addition to the publication, there will be an interactive presentation (poster) in the venue. Below is a brief abstract.
In this paper is presented a pragmatic data model for creating and managing linked contextual and material objects, the design process and the reasons why it was developed. The model was created to meet the needs of private archives and digital archive services. The design goals were flexibility, cost-efficiency and suitability for daily use. The basis of the model is to use contextual objects to describe the archive objects; should they be text documents, moving image, audio or any other type of content to be preserved. By linking the contextual objects such as events, places, agents and actions, the redundancy of archive data can be minimized. The objects gain more informational value because the linking forms a network of connected objects. The data model was based on the national and international metadata standards as well as best practices from private archives. It was implemented using Fedora Commons’ object modeling features as a part of the ongoing Open Source Archive project.
The second paper is Micro-services based distributed workflow for digital archives by Heikki Kurhinen (developer at Otavan Opiston and working on a thesis at MAMK Uni. of Applied Sciences) and Mikko Lampi. The paper is presented as a traditional conference presentation. The workflow engine itself is made available open source during 2014. If you’re interested, drop me an email or comment. Below is a brief abstract.
Managing the costs and the workloads in digital preservation requires automation and supportive tools. Micro-services is a well-tested and widely adapted architecture, proven in archive systems and operating systems like Linux and UNIX. The automation level can be increased by combining the services into workflows and making the processing distributed. Resource consuming tasks such as ingest, migration and format conversion can be streamlined with this kind of approach.
This paper is about the development of a workflow engine prototype for micro-services based distributed processes in digital archives. The prototype is demonstrated with a simple use case of digital content ingest workflow. The design goal was to support work done in the digital archive developments and to provide a simple and extendable tool for processing the digital content.
There are some other publications coming later this spring by some thesis students. The thesis about above workflow development and modeling will be there. Hope to see some of our readers at Archiving 2014.
