title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 15 (EANJ_FIGURE_15):
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 an anthropomorphic jade object (Object ID: EANJ_FIGURE_15).

1.2

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

 

2. Access and Use Guidelines

2.1 Access Restrictions

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

2.2 Application Requirements

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

2.3 Usage Boundaries

This dataset is restricted 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 and use beyond the scope of academic comparison is strictly prohibited.

 

3. Dataset Composition

3.1 Overall Image Documentation

Includes full-resolution images capturing the object from front, reverse, and side orientations, as well as macro images of local features (such as perforation structures, surface erosion conditions, and observable manufacturing-related traces), documenting the object’s overall proportional relationships and geometric contour structure.

3.2 Metric Reference Images

Includes images incorporating a metric scale for basic dimensional and proportional reference:



Length: 9.4 cm

Width: 2.5 cm

Thickness: 1.2 cm

Weight: 47 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

Includes multi-angle high-magnification macro images documenting the following directly observable visual features:



Perforation channels and drilling structures

Surface erosion and depositional conditions

Identifiable manufacturing or finishing traces

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 publication and presentation. Each image has a resolution of approximately 42 megapixels.

5.2

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

5.3

No physical handling, cleaning, or surface intervention was applied to the object during the imaging process.

5.4

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

 

6. Compliance and Due Diligence

6.1

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

6.2

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

6.3

This dataset is released as a non-interpretive original visual record. It does not constitute any academic conclusions regarding the object’s function, cultural attribution, chronological placement, or typological classification, nor does it represent the position or viewpoint of any institution or individual.
