Over the next year I’m creating a plan for investigating and implementing digital curation micro-services in some form. A first step in this project is a learning environment on the topic.

PLE: Curation Micro-Services
03-Jan-11Bookmark: Archivematica
10-Nov-10Archivematica is an open source digital preservation platform using the micro-services design idea “that allows users to process digital objects from ingest to access in compliance with the ISO-OAIS functional model”. Tweet
The MetaArchive Cooperative has released a Guide to Distributed Digital Preservation: This volume is devoted to the broad topic of distributed digital preservation, a still-emerging field of practice for the cultural memory arena. Replication and distribution hold out the promise of indefinite preservation of materials without degradation, but establishing effective organizational and technical processes to [...]
Scanned Master Files Compared

Effects of Open Source on Preservation
05-Jan-09David Rosenthal has a detailed and useful analysis of the value of open format specifications for preservation: If we plot the quality achieved by a newly created renderer for a format against the cost of creating it we will get an S curve. A certain amount of money is needed to get to a barely [...]
Usability Over Time
01-Jan-09Found this useful idea by Chris Rusbridge from a year-end review by Jill Hurst-Wahl: It’s not just the language that makes digital preservation unconvincing to the decision maker. Part of the problem is that digital preservation describes a process, and not an outcome. … So I would argue that outcome-related phrases like “long term accessibility” [...]
Preserving Data in a Hostile Environment

The archives invoked its emergency plan to deal with problems in transferring two types of electronic files: a huge [...]
Reading a press release out of UCSD, this comment from the Blue Ribbon Task Force on Sustainable Digital Preservation and Access [pdf] caught my eye: A recent study by the International Data Corporation (IDC) said that in 2007, the amount of digital data began to exceed the amount of storage to retain it, and will [...]
