RTT Operator Lab — archive_org Module

labs/operator_lab.md#

Overview#

In this lab, you will use the Internet Archive to analyze how a webpage changes over time.
You will practice all six RTT operators:

  1. METADATA_OPERATOR
  2. WAYBACK_OPERATOR
  3. LINEAGE_OPERATOR
  4. COLLECTION_OPERATOR
  5. PRESERVATION_OPERATOR
  6. DRIFTBOUND_RETRIEVAL_OPERATOR

Your goal is to determine which snapshot is the most reliable version of the webpage.

All analysis must be structural, not content‑based.

Scenario#

You will analyze the following synthetic webpage:

Target URL:
https://archive.org/details/sample-training-page

Snapshots available:
2013, 2016, 2019, 2023

1. METADATA_OPERATOR#

Visit the target page (live or archived) and identify:

  • substrate type (HTML, PDF, image, OCR, mixed)
  • regime (institutional, news, scholarly, technical, cultural)
  • drift sensitivity (low, medium, high)
  • coherence (low, medium, high)

Your notes:#

Substrate:
Regime:
Drift sensitivity:
Coherence:

2. WAYBACK_OPERATOR#

Go to the Wayback Machine and list the snapshots.

Tasks#

  1. Write down the snapshot years.
  2. Compare each pair of snapshots and classify drift:
    • none
    • minor
    • moderate
    • high
  3. Identify any continuity breaks (missing years).

Your notes:#

Snapshot years:
Drift map:
Continuity breaks:

3. LINEAGE_OPERATOR#

Compare the structure of the snapshots.

Look for:

  • template changes
  • navigation changes
  • layout shifts
  • CMS migrations
  • persistent elements (continuity kernel)

Your notes:#

Structural changes:
Continuity kernel:
Regime shifts:

4. COLLECTION_OPERATOR#

Identify the Internet Archive collection the page belongs to.

Then list:

  • collection ID
  • coherence clusters
  • related objects
  • regime profile

Your notes:#

Collection ID:
Coherence clusters:
Related objects:
Regime profile:

5. PRESERVATION_OPERATOR#

Evaluate the stability of the snapshots.

Consider:

  • substrate stability
  • drift risk
  • mixed layers
  • stability score (qualitative)

Your notes:#

Format:
Stability:
Drift risk:
Multi-layer notes:

6. DRIFTBOUND_RETRIEVAL_OPERATOR#

Combine all previous steps to determine:

  • earliest stable version
  • most reliable version
  • key structural changes
  • warnings
  • final answer

Your notes:#

Earliest stable version:
Most reliable version:
Key changes:
Warnings:
Final answer:

7. Reflection#

Write a short paragraph:

What did you learn about how webpages change over time?
