title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 01 (EANJ_FIGURE_01):
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 documenting a single anthropomorphic jade object (Object ID: EANJ_FIGURE_01).

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

 

2. Access and Usage Conditions

2.1 Access Restriction

In consideration of data security, academic standards, and controlled usage boundaries, all 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 should include a brief statement of research purpose and institutional affiliation.

2.3 Usage Boundaries

This dataset is intended solely for academic research, teaching reference, visual documentation, and non-interpretive comparative analysis.Without explicit authorization from the data publisher, any form of commercial use, non-academic dissemination, redistribution, or reuse beyond scholarly comparative contexts is strictly prohibited.

 

3. Dataset Composition

3.1 Comprehensive Visual Documentation

The dataset includes full-resolution images captured from frontal, reverse, and lateral orientations, as well as macro images of localized features (such as perforation structures, surface alteration states, and observable modification-related traces). These images document the object’s overall proportional relationships and geometric contour structure.

3.2 Metric Reference Images

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



Length: 9.8 cm

Width: 3.4 cm

Thickness: 3.1 cm

Weight: 189 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 values.

3.3 Macro Imaging Records

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



Perforation channels and through-perforation structures (if present)

Surface alteration, erosion, and depositional conditions

Identifiable modification 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 image data were recorded in RAW format and subsequently converted to JPEG files for dataset release 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 representation of the material.

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

5.4 If post-processing was performed, it was strictly limited to global exposure and white balance adjustments, with the sole purpose of accurately reflecting the visual condition of the object’s material.

 

6. Compliance and Due Diligence

6.1 The organization, digitization, and release 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 conducted, including evaluations of usage boundaries, potential misinterpretation risks, and consistency with academic standards.

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