OpenLink Data Spaces

What are Data Spaces?

A named structured data cluster within a distributed data network where each item of data (each "datum") has a unique identifier. Fundamental characteristics of data spaces include:

In relation to the Web, data spaces provide clustered points of access to data object; basically, they provide structured data access partitioning just as 'machine names' provide name oriented partitioning for DNS and 'table names' the same for database systems.

Why are Data Spaces important?

Data Spaces provide a powerful conceptual model based virtualization layer that sits atop heterogeneous data sources. They enable the creation, publication, and general management of structured data items (data objects) from a pool of disparate data sources. Examples include:

What is OpenLink Data Spaces?

ODS is an industry standards-compliant data space platform that includes a broad collection of distributed collaborative applications covering: blogs, wikis, shared bookmarks, file management, calendaring, email, photo galleries, discussion forums, polls, and more.

Every item of data within an ODS instance is endowed with a de-referenceable URI. This enables any HTTP-compatible client to obtain a negotiated representation of the description of any ODS data item.

Challenges Alleviated via ODS

User content across the Web, both Intranet and Extranet, is growing exponentially, while time, attention, and comprehension of the resulting data streams is at best static, and typically shrinking. Compounding the problem is the fact that the exponential growth of user generated data has resulted in a proliferation of data silos, due to the popularity of Web 2.0 solution patterns.

All of this is happening at a time when individuals and organizations alike are seeking to do more with less, by exploiting the agility-producing powers of "Open Data Access" across enterprise and/or Web domains.
