A Marriage of Convenience: the Possibilities of Service-oriented Architecture and Web 2.0 for Digital Archaeology
Using networks to connect resources
• Grids to allow virtual computing across “admin domains”– Virtual digital libraries,
virtual museums, virtual observatories
• Technology that was first adopted in sciences…
E-Science: Building bridges
(with thanks to Tobias Blanke, King’s College London)
“the development and deployment of a networked infrastructure and culture through which resources – (…) – can be shared in a secure environment, and in which new forms of collaboration can emerge, and new and advanced methodologies explored.”
- Sheila Anderson Director, Centre for e-Research, King’s College London, 2007

What is SOA?
“a collection of loosely-coupled, distributed services which communicate and interoperate via agreed standards. The combination of a service and standards-based approach can result in a directory of reusable service components which together can be employed to enhance existing networked applications or build new applications.”

A Marriage of Convenience: the Possibilities of Service-oriented Architecture and Web 2.0 for Digital Archaeology
Enter archaeology…
Multiple ways of accessing multiple information
• SMRs
• Digital Libraries
• Grey Lit.
• Individual site records
• Government agencies
• Tag clouds
• Blogs
• Wikis
Different file structures and metadata
Created by different kinds of user
Often constrained by modern national boundaries
Some aggregate data, some deliver data from a single source
A Marriage of Convenience: the Possibilities of Service-oriented Architecture and Web 2.0 for Digital Archaeology
Attempts to provide real-time access to a range of sources of information
Uses Grid middleware
Deploys different services
Is an example of a top down approach
Operates accepted standards
QuickTime™ and aTIFF (Uncompressed) decompressor
are needed to see this picture.
A Marriage of Convenience: the Possibilities of Service-oriented Architecture and Web 2.0 for Digital Archaeology
Digital legacy of the Barrington Atlas
Users can add their own data on, or about, Greco-Roman placenames
Flexible, works at different scales
Is an example of a bottom up approach

The SOA approach
Benefits
Bringing together data and tools wherever/whoever they originate from
Simplify the process of acquiring and publishing data
Drawbacks People
Data
Computation
Trust/subversion of peer-review(?)
Security
Misuse of data
Web 2.0
