ETSI Specification Retrieval

Overview

Retrieve comprehensive metadata for ETSI (European Telecommunications Standards Institute) specifications including latest version, full title, publication date, download URLs, and version history.

Quick Start

To get metadata for an ETSI specification:

uv run scripts/get_etsi_spec.py <spec-number>

Accepted formats:

  • 103224 (six digits, defaults to TS type)
  • 103 224 (three digits, space, three digits)
  • ETSI TS 103 224 (with prefix)
  • EG 202 396-3 (document type + spec + part)
  • TR 103 907 (document type + six digits)
  • ES 200 381-1 (document type + six digits + part)

Examples:

# TS (Technical Specification)
uv run scripts/get_etsi_spec.py 103224
uv run scripts/get_etsi_spec.py ETSI TS 103 224

# EG (ETSI Guide)
uv run scripts/get_etsi_spec.py EG 202 396-3

# TR (Technical Report)
uv run scripts/get_etsi_spec.py TR 103 907

# ES (ETSI Standard)
uv run scripts/get_etsi_spec.py ES 200 381-1

ETSI Document Types

ETSI publishes multiple document types, each with different purposes:

Type Name Purpose
EN European Standard Harmonized standard
ES ETSI Standard Technical specification for market implementation
EG ETSI Guide Guidance document
TS Technical Specification Technical specification
TR Technical Report Informational report
SR Special Report Temporary or specific-use document
GS Group Specification Specification from a specific group
GR Group Report Report from a specific group
PAS Publicly Available Specification Document for public use

Specification Numbering

ETSI specifications follow this pattern:

  • Document type: EN, ES, EG, TS, TR, SR, GS, GR, or PAS
  • Prefix: Series identifier (3 digits) - indicates technical area
  • Number: Unique identifier within series (3 digits)
  • Part: Optional component (-1, -2, -3, etc.) for multi-part standards
  • Full format: <doc_type> XXX YYY[-Z]

Common series prefixes:

  • 200: General telephony requirements
  • 103: Speech and multimedia Transmission Quality (STQ)
  • 123: System architecture
  • 128: Security
  • 133: Protocol stack
  • 202: Network protocols

Examples:

  • ETSI TS 103 224: TS type, series 103, specification 224
  • EG 202 396-3: EG type, series 202, specification 396, part 3
  • ES 200 381-1: ES type, series 200, specification 381, part 1

Script Output

The script returns:

  • Latest version number (e.g., V1.7.1)
  • Release code (e.g., 60 for 60th revision)
  • Full specification title
  • Publication date
  • Direct download URL for PDF
  • Version history (all available versions)

Example output for ETSI TS 103 224:

How It Works

The script retrieves ETSI specification metadata through these steps:

  1. Parse specification number from various input formats, including document type (EN/ES/EG/TS/TR/SR/GS/GR/PAS) and optional part (-1, -2, etc.)

  2. Construct delivery directory URL using ETSI's predictable structure:

    • Pattern: https://www.etsi.org/deliver/etsi_<type>/<prefix>00_<prefix>99/<full_spec>/
    • Example for TS 103 224: https://www.etsi.org/deliver/etsi_ts/103200_103299/103224/

  3. Scrape version directories from delivery page

    • Format: XX.YY.ZZ_AA (major.minor.patch_release)
    • Example: 01.07.01_60 = version 1.7.1, release 60
    • Some specs may use different formats (e.g., no release code)

  4. Identify latest version by sorting directories

  5. Construct PDF download URL by trying common filename patterns:

    • <type>_<spec>v<version_no_dots>p.pdf
    • <type>_<spec>v<version_no_dots>.pdf
    • <spec>v<version_no_dots>.pdf
    • EG specs may use .m.pdf extension instead of .p.pdf

  6. Extract metadata from PDF:

    • Parse PDF metadata for title and creation date
    • If title missing, extract from first page content

Limitations

  1. Spec numbering: Not all specification numbers exist or follow expected patterns. Some specs may be:

    • Withdrawn
    • Superseded by newer versions
    • Located in different directory structures
    • Have unique numbering schemes

  2. URL variations: ETSI delivery URLs may vary by document type and series. The script tries common patterns but may not handle all cases.

  3. Parts detection: Multi-part standards (e.g., ES 200 381-1, -2, -3) are detected from spec number but all parts must be queried separately for complete version history.

  4. EG specifications: EG specs sometimes use different PDF file extensions (e.g., .m.pdf instead of .p.pdf).

  5. Multi-part spec directories: Multi-part specifications like "EG 202 396-3" may use directory naming that differs from single-part specs. The script attempts to find the correct directory by:

    • Checking if the full spec number (including part) appears in directory names
    • For single-part specs, using standard 100-number range calculation

  6. Known issue with EG 202 396-3: This specification exists at https://www.etsi.org/deliver/etsi_eg/202300_202399/20239603/ but the script's range detection logic may not always identify the correct directory for multi-part EG specifications. Manual verification may be required for such cases.

Manual Retrieval Fallback

If the script fails, retrieve metadata manually:

  1. Find spec directory: Browse to https://www.etsi.org/deliver/etsi_<type>/

    • Where <type> is ts, es, eg, tr, etc.

  2. Locate spec number in the appropriate prefix range directory (e.g., 103000_103099/)

  3. List version directories (sorted alphabetically = chronological)

    • Latest version is last directory in list

  4. Download PDF from version directory

    • Try common filename patterns

  5. Extract metadata from PDF:

    • Title: First page or PDF metadata
    • Date: PDF creation date (/CreationDate field)
