EANJ_ZOOMORPHIC_30: Low-Resolution Visual Record of a Zoomorphic-Form Jade Object (Public Preview)

1. Dataset Context

This dataset forms part of a systematic digital visual archiving project. It documents a single zoomorphic-form jade object (EANJ_ZOOMORPHIC_30) through multi-view, low-resolution imagery and is published as the public preview layer within a tiered data structure.

2. Research Purpose

This dataset is generated through standardized imaging and documentation procedures to provide a verifiable baseline of visual data. It supports research conducted under user-defined methodological frameworks, including:

• Morphological comparative studies
• Teaching and illustrative purposes
• Non-invasive, image-based analysis

The low-resolution images are intended for public preview only.
The corresponding high-resolution original imagery (approximately 42 megapixels per image) is published as a separate record (Record B) under restricted access.

3. Data Description

3.1 Object Information

Zoomorphic-form jade object (single specimen)

Approximate measurements:

• Length: 7.6 cm
• Width: 2.8 cm
• Thickness: 2.3 cm
• Weight: 86 g

Note: These values are derived from image-based measurements and are provided for reference only. They do not constitute precise metrological data.

3.2 Image Content

The low-resolution public preview includes four representative images selected for structural identification and general visual reference:

Overall views

• EANJ_ZOOMORPHIC_30_OVERALL_A
• EANJ_ZOOMORPHIC_30_OVERALL_C

Macro views

• EANJ_ZOOMORPHIC_30_MACRO_A
• EANJ_ZOOMORPHIC_30_MACRO_F

This public preview represents a subset of the complete dataset.
The full high-resolution Record B contains a broader range of viewing angles and more detailed visual documentation.

3.3 Imaging Method

• Equipment: Full-frame digital camera with a 90 mm macro lens
• Format: RAW capture → JPEG export for publication
• Lighting: Controlled lighting environment
• Background: Neutral background
• Physical intervention: None
• Post-processing: Limited to global exposure and white balance adjustments

4. Data Access & Structure

This dataset follows a tiered publication structure:

• Record A: Low-resolution public preview (this record)
• Record B: High-resolution original imagery (restricted access)

This structure distinguishes between public-facing visual materials and research-grade datasets.

5. Usage & Licensing

This dataset is intended for academic research, teaching purposes, and non-interpretive visual and comparative analysis.

Any use beyond these purposes—including commercial applications, redistribution, or dissemination in non-academic contexts—requires prior authorization.

6. Notes on Interpretation

This dataset provides only directly observable visual information derived from the images. It does not contain any interpretive, attributive, or historical assessments.

7. Access Information

The complete high-resolution dataset (Record B) is published as a separate record under restricted access.
