title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 11 (EANJ_FIGURE_11):
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_11).

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 in support of non-interpretive morphological observation, traceological research, and material-related analytical work.

 

2. Access and Use Information

2.1 Access Restrictions

For reasons of data security, academic standards, and controlled boundaries of use, 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 statement of research purpose and institutional affiliation.

2.3 Use Boundaries

This dataset is intended exclusively for 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 Overall Image Documentation

The dataset includes full-resolution images capturing the object from frontal, reverse, and profile orientations, as well as macro images of local features (such as perforation structures, surface erosion conditions, and observable manufacturing-related traces). These images document the object’s overall proportional relationships and geometric outline in full resolution.

3.2 Measurement Reference Images

Images incorporating a metric scale are provided for basic quantitative reference of dimensions and proportions:



Length: 6.2 cm

Width: 1.6 cm

Thickness: 1.6 cm

Weight: 29 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 Records

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



Perforation 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 equipped 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 used to minimize environmental interference with the visual appearance of the material.

5.3

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

5.4

If any post-processing was applied, it was strictly limited to global exposure and white balance correction, with the sole aim 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 evaluations of usage boundaries, potential risks of misinterpretation, and consistency with academic standards.

6.3

This dataset is released as a non-interpretive visual record and does not constitute any academic conclusions regarding the object’s function, cultural attribution, chronological assessment, or typological classification. It does not represent the position or viewpoint of any institution or individual.
