Preserve, then make accessible

We keep digital collections safe — then make them accessible.

Long-term preservation and access are two halves of one lifecycle. Data Tango does both: we keep digital and digitized material intact over time, then build the layer that makes it accessible to the world.

What we do

Two moves that only make sense together.

Preservation and access are not separate service lines — they are the two halves of one lifecycle. You keep material safe, and then you make it accessible.

Preserving data & media

We keep digital and digitized material intact and usable over the long term — ingest, fixity checking, format identification and normalization, and workflows built to survive decades, not quarters.

Solutions for access

Then we build the layer that makes preserved material accessible — viewers, APIs, and interfaces that make collections explorable, with IIIF as the headline capability you can try right here.

The value is in the connection between the two: few do preservation and access end to end. See the access half in action

The playground

Paste a manifest. Watch it render.

Our live IIIF viewer comes loaded with three collection items from libraries and museums — and it will just as happily render a manifest from your own institution. This is the access half, working in your browser.

  • Deep zoom
  • Multi-canvas navigation
  • Side-by-side comparison
  • Your own institution's manifest

A demonstration

Preservation and access, on a single object.

A public-domain work, served through the IIIF Image API and presented the way a gallery would: matted, framed, and captioned with its provenance.

Find our work

We'd rather show than tell.

Data Tango is early, with no client logos to parade. We think that's the wrong proof anyway. Judge us on work you can open and inspect.

Contact

Tell us what you need to keep — and make accessible.

Whether it's a collection that needs preserving, material that needs access, or a IIIF question you've been circling, we'd like to hear about it.
