OASIS Open Standard · Universal Data Access

One path to all
of your data,
everywhere.

Single Namespace is an open standard that gives every file, object, and dataset a single canonical address — resolved transparently across file systems, object stores, HPC, and multi-cloud, with no data migration.

01The Challenge

Fragmented data is one of computing's most persistent problems.

Research, healthcare, and AI workloads increasingly demand exascale datasets — yet that data is scattered across incompatible systems with no common way to reach it.

01

Data is fragmented by design

Datasets live in incompatible silos across HPC scratch, object stores, and a dozen cloud regions — each with its own access path.

02

Migration is the only answer

Moving data between vendor platforms is slow, expensive and risky, and it has to be repeated every time a workload moves.

03

Stewardship breaks down

Silos make governance, provenance, and compliance nearly impossible to maintain consistently at scale.

02The Standard

Cross-compatibility across the entire storage ecosystem.

By standardizing four layers, the specification lets vendors build interoperable solutions where components can be swapped without migrating a single byte.

01

Interactions & Protocols

Standardize how clients and storage systems communicate across tiers, regions, and vendors.

02

Formats & Behaviors

Define consistent data formats and expected behaviors so components become interchangeable.

03

APIs & Interfaces

Publish open, royalty-free APIs that let vendors build interoperable, swappable solutions.

04

Cross-platform Access

Reach data from HPC to cloud through one namespace — with no migration required.

03Get Involved

Two ways to participate.

For builders
