title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 14 (EANJ_FIGURE_14):
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 a single anthropomorphic jade object (Object ID: EANJ_FIGURE_14).

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 contours.

3.2 Metric Reference Images

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



Length: 4.7 cm

Width: 4.0 cm

Thickness: 4.0 cm

Weight: 78 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 Methods and Processing

5.1All images were captured using a full-frame camera equipped with a 90 mm macro lens. Original data were recorded in RAW format and subsequently converted to JPEG files for dataset publication and display. Each image has an approximate resolution of 42 megapixels.

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

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

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

 

6. Compliance and Due Diligence Statement

6.1The organization, digitization, and publication of this dataset adhere to fundamental principles of academic data management and research ethics.

6.2Prior to publication, internal compliance and risk assessments were conducted, including evaluation of data use boundaries, potential misinterpretation risks, and consistency with academic standards.

6.3This dataset is released as a non-interpretive original visual record. It does not constitute, imply, or support any 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.
