Tika

The Tika node extracts format metadata and embedded text from virtually any file type using Apache Tika — images (EXIF), audio/video containers, PDFs and Office documents.

Kind

tika

Applies to

Image, Audio, Video, Document

Inputs

None

Output keys

tika_flags (String), tika_content (String, extracted text)

Requirements

CPU only — Apache Tika is pure JVM, no native dependency or external service.

Persists to

asset_json_comp + asset_node_result ledger

Configuration

No custom options beyond the common node flags — Tika auto-detects the format and applies the appropriate parser.

Use Cases

  • Universal metadata extraction — pull EXIF, codec, author, page-count and similar fields across many formats in one node.

  • Embedded text indexing — extract text from PDFs and Office documents for search.

  • Format triage — a cheap first-pass over heterogeneous ingest.
