# ISCC-LAB - Semantic-Code Text
`iscc-sct` is a **proof of concept implementation** of a semantic Text-Code for the
[ISCC](https://core.iscc.codes) (*International Standard Content Code*). Semantic Text-Codes are
short identifiers created from text documents that preserve similarity (in hamming distance)
for semantically similar cross-lingual text inputs.
## What is the ISCC
The ISCC is a combination of various similarity preserving fingerprints and an identifier for
digital media content.
ISCCs are generated algorithmically from digital content, just like cryptographic hashes. However,
instead of using a single cryptographic hash function to identify data only, the ISCC uses various
algorithms to create a composite identifier that exhibits similarity-preserving properties (soft
hash or Simprint).
The component-based structure of the ISCC identifies content at multiple levels of abstraction. Each
component is self-describing, modular, and can be used separately or with others to aid in various
content identification tasks. The algorithmic design supports content deduplication, database
synchronization, indexing, integrity verification, timestamping, versioning, data provenance,
similarity clustering, anomaly detection, usage tracking, allocation of royalties, fact-checking and
general digital asset management use-cases.
## ISCC Status
The [ISCC](https://iscc.codes) is an ISO Standrad published under
[ISO 24138:2024](https://www.iso.org/standard/77899.html) - International Standard Content Code
within [ISO/TC 46/SC 9/WG 18](https://www.iso.org/committee/48836.html).
The algorithms of this `iscc-sct` are experimental and not (yet) part of the official standard.
