title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 04 (EANJ_FIGURE_04):
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 raw visual data documenting a jade object of anthropomorphic form (Object ID: EANJ_FIGURE_04).

1.2 This dataset constitutes a component unit within an ongoing, systematically constructed 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 Guidelines

2.1 Access Restrictions

For reasons of data security, academic standards, and controlled usage boundaries, the full-resolution original image files included in this dataset are designated as 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 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 Record

The dataset includes high-resolution images documenting the front, back, sides, and localized features through macro photography (such as perforation structures, surface erosion conditions, and observable manufacturing-related traces).All images record the object’s overall proportional relationships and geometric contour structure at full resolution.

3.2 Measurement Reference Images

Images incorporating metric scale markers are included to provide quantitative reference for basic dimensions and proportions:



Length: 7.4 cm

Width: 3.0 cm

Thickness: 1.3 cm

Weight: 39 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 channels and piercing structures

Surface erosion and depositional conditions

Identifiable manufacturing or finishing traces

5. Imaging Methods 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 display.Each image has an approximate resolution of 42 megapixels.

5.2 Photography was conducted under controlled lighting conditions, with a neutral background employed to minimize environmental influence on the visual appearance of the material.

5.3 No physical handling, cleaning, or surface intervention of any kind was performed on the object during imaging.

5.4 Any post-processing was strictly limited to global exposure and white balance adjustments, with the objective of accurately representing 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 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 as non-interpretive raw visual documentation. It does not constitute 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.
