title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 03 (EANJ_FIGURE_03):
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 jade anthropomorphic object (Object ID: EANJ_FIGURE_03).

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

 

2. Access and Use Conditions

2.1 Access Restrictions

For reasons of data security, academic standards, and controlled use boundaries, the full-resolution original image files included 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 Use 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 Comprehensive Image Documentation

The dataset includes full-resolution images documenting the object from frontal, reverse, and lateral orientations, as well as macro images of localized features (such as perforation structures, surface erosion states, and observable traces related to manufacture). These images record the object’s overall proportions and geometric contours in detail.

3.2 Metric Reference Images

Images incorporating a metric scale are included for basic dimensional and proportional reference:



Length: 7.3 cm

Width: 3.2 cm

Thickness: 1.9 cm

Weight: 59 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 Imaging Records

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



Perforations and perforation channel structures

Surface erosion and depositional conditions

Identifiable traces related to shaping or finishing

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 to minimize environmental interference with the visual appearance of the material.

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

5.4 Any post-processing was limited strictly to global exposure and white balance adjustments, with the sole aim of accurately representing the object’s visual state.

 

6. Compliance and Due Diligence

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

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

6.3 This dataset is published solely as a non-interpretive record of raw visual data. 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.
