## Introduction to Apache Any23

### Library

Anything To Triples (any23) is a library, a web service and a command line tool that extracts structured data in RDF format from a variety of Web documents. Currently it supports the following input formats:

- RDF/XML, Turtle, Notation 3
- RDFa with RDFa1.1 prefix mechanism
- Microformats1 and Microformats2: hAdr, hCard, hCalendar, hEntry, hEvent, hGeo, hItem, hListing, hProduct, hProduct, hRecipie, hResume, hReview, License, Species, XFN, etc
- JSON-LD: JSON for Linking Data. a lightweight Linked Data format based on the already successful JSON format and provides a way to help JSON data interoperate at Web-scale.
- HTML5 Microdata: (such as Schema.org)
- CSV: Comma Separated Values with separator autodetection.
- Vocabularies: Extraction support for Dublin Core Terms, Description of a Career, Description Of A Project, Friend Of A Friend, GEO Names, ICAL, lkif-core, Open Graph Protocol, BBC Programmes Ontology, RDF Review Vocabulary, schema.org, VCard, BBC Wildlife Ontology and XHTML... and more!
- YAML: human friendly data serialization standard for all programming languages.
- Additionally, as of 2.1 Any23 provides functionality to extract triples using the Open Information Extraction (Open IE) system. The Open IE system runs over sentences and creates extractions that represent relations in text, in the case of Any23, this results in triples.

A detailed description of available extractors is here.

Apache Any23 is written in Java and licensed under the Apache License v2.0. Apache Any23 can be used in various ways:

- As a library in Java applications that consume structured data from the Web.
- As a command-line tool for extracting and converting between the supported formats.
- As online service API available at any23.org.
