title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 05 (EANJ_FIGURE_05):
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_05).

1.2

This dataset constitutes a component of an ongoing, systematically constructed digital archiving initiative. 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 Conditions

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 designated as 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 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 beyond the scope of academic comparison is strictly prohibited.

 

3. Dataset Composition

3.1 Overall Image Documentation

Includes full-resolution images from frontal, rear, and lateral orientations, as well as macro images of localized features (such as perforation structures, surface erosion states, and observable manufacturing-related traces), documenting the object’s overall proportions and geometric contours.

3.2 Metric Reference Images

Includes images with metric scale bars for basic dimensional and proportional reference:



Length: 5.5 cm

Width: 1.5 cm

Thickness: 2.2 cm

Weight: 35 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 perforation 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 presentation. Each image has an approximate resolution of 42 megapixels.

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

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

5.4 If any post-processing was applied, it was strictly limited to global exposure and white balance correction, with the objective of accurately reflecting the object’s visual condition.

 

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 reviews 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 conclusion regarding the object’s function, cultural attribution, chronology, or typological classification, nor does it represent the position of any institution or individual.
