OmniClass XML Download & Data Access

Looking for OmniClass in XML Format?

If you're searching for OmniClass in XML format, you're likely looking for table classifications you can integrate into software.

There is no free OmniClass XML download. OmniClass is a proprietary standard published and maintained by CSI. Access requires licensing.

The Problem with Static XML Files

OmniClass is updated regularly by CSI. A xml file from 2020 doesn't reflect 2021 updates. The moment CSI publishes a new edition, your xml file is outdated.

Static xml files create multiple problems:

• Stale data — XML files go stale the moment CSI publishes a new OmniClass edition
• No edition tracking — You don't know which OmniClass edition the file represents or what changed
• No cross-references — Static files lack governed crosswalks between OmniClass, MasterFormat, and UniFormat
• Legal risk — Unauthorized OmniClass xml files found online violate CSI's intellectual property rights

The Live Alternative to XML Files

The Construction Standard provides licensed access to OmniClass through CSI Dynamic Standards. The platform beats any static xml file:

• Always current — Reflects the latest CSI-approved OmniClass classifications and updates automatically when CSI publishes changes
• Searchable — Search by table number, entry code, or classification keyword, browse the full hierarchy, filter and bookmark frequently-used entries
• Cross-referenced — Cross-reference OmniClass entries to MasterFormat specification sections and UniFormat building elements to bridge lifecycle classifications across all three standards
• Edition-aware — See what changed between OmniClass editions, know which edition you're using, and avoid edition mismatches across your project team

OmniClass Data for Software Integration

If you need OmniClass data in XML format for software integration, The Construction Standard provides licensing options for platforms that need to integrate CSI standards data. Licensed access ensures your platform uses current, authorized OmniClass data.
