title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 12 (EANJ_FIGURE_12):
High-Resolution Digital Documentation of Morphology, Perforation Structures, Surface Condition, and Observable Modification Traces

description: 1. Core Statement

1.1

This record contains high-resolution original visual data of a jade object with an anthropomorphic form (Object ID: EANJ_FIGURE_12).

1.2

This dataset constitutes a component of an ongoing, systematic digital archiving initiative. It is released as foundational research data intended to provide high-fidelity visual evidence in support of non-interpretive morphological observation, traceological research, and material-related analytical work.

 

2. Access and Use Conditions

2.1 Access Restrictions

For reasons of data security, academic standards, and controlled use boundaries, the full-resolution original image files contained in this dataset are designated as restricted access.

2.2 Application Requirements

Access requests must be submitted via the Zenodo platform and should include a brief statement of research purpose and institutional affiliation.

2.3 Use Limitations

This dataset is strictly limited to academic research, teaching reference, visual documentation, and non-interpretive comparative analysis.Without explicit authorization from the dataset publisher, any form of commercial use, non-academic dissemination, redistribution, or reproduction beyond the scope of academic comparison is strictly prohibited.

 

3. Dataset Composition

3.1 Comprehensive Image Documentation

The dataset includes full-resolution images from frontal, reverse, and lateral orientations, as well as macro images of localized features (such as perforation structures, surface erosion conditions, and observable traces related to manufacture), documenting the object’s overall proportional relationships and geometric outline.

3.2 Metric Reference Images

Images incorporating a metric scale are provided for basic dimensional and proportional reference:



Length: 6.1 cm

Width: 3.2 cm

Thickness: 1.0 cm

Weight: 26 g


Note: Due to the complexity of the object’s contours and volumetric structure, the listed measurements are approximate and should not be regarded as precise.

3.3 Macro Image Documentation

Multi-angle, high-magnification macro images are included to record the following directly observable visual features:



Perforation and bore structures

Surface erosion and depositional conditions

Identifiable traces related to manufacture or finishing

5. Imaging Methodology and Processing

5.1

All images were captured using a full-frame camera paired with a 90 mm macro lens. Original data were recorded in RAW format and converted to JPEG files for dataset release and presentation. Each image has a resolution of approximately 42 megapixels.

5.2

Photography was conducted under controlled lighting conditions, using a neutral background to minimize environmental interference with the visual presentation of the material.

5.3

No physical handling, cleaning, or surface intervention was performed on the object during the imaging process.

5.4

Where post-processing was applied, it was strictly limited to global exposure and white-balance adjustments, with the sole objective of accurately reflecting the visual condition of the material.

 

6. Compliance and Due Diligence Statement

6.1

The compilation, digitization, and publication of this dataset adhere to fundamental principles of academic data management and research ethics.

6.2

Prior to release, internal compliance and risk assessments were completed, including evaluation of usage boundaries, potential risks of misinterpretation, and consistency with academic standards.

6.3

This dataset is published exclusively as a non-interpretive visual record. It does not constitute, imply, or support any academic conclusions regarding the object’s function, cultural attribution, chronology, or typological classification, nor does it represent the position of any institution or individual.
