Submitting eprints

This guide covers the eprint submission process in detail.

Before you submit

Ensure you have:

• A PDF of your eprint (maximum 50 MB)
• Required metadata: title, abstract, keywords
• An AT Protocol account (e.g., Bluesky)
• Co-author consent for multi-author submissions

Submission workflow

Step 1: Authentication

Click "Sign In" and authenticate with your PDS. Chive uses OAuth 2.0 for authentication; your credentials are never stored on Chive servers.

Step 2: Start submission

Click "Submit Eprint" to open the submission form. The form has four sections.

Step 3: Basic information

Field	Required	Description
Title	Yes	Full title of your eprint. LaTeX math is detected and rendered.
Abstract	Yes	Rich text summary supporting formatting, LaTeX, and references
Keywords	Yes	At least one author-provided keyword
License	Yes	Creative Commons license (CC-BY recommended)

Titles containing LaTeX expressions (e.g., $\alpha$-decay) are automatically detected. A rich text version (titleRich) is generated with the math rendered inline.

Abstracts support rich text items including plain text, LaTeX math, entity references (knowledge graph nodes, other eprints, authors), code blocks, headings, and lists.

Step 4: Authors

Add all authors with their affiliations:

1. Click "Add Author"
2. Enter name and institutional affiliation
3. Add sub-units within the affiliation (e.g., University > School > Department > Lab)
4. Optionally link to ORCID
5. Assign CRediT contribution roles (conceptualization, methodology, writing, etc.)
6. Drag to reorder authors
7. Mark corresponding author

Affiliations are stored as hierarchical trees linked to ROR identifiers and knowledge graph institution nodes.

Step 5: Upload files

PDF upload

Drag and drop your PDF or click to select. The file uploads directly to your PDS. Chive stores only a reference (BlobRef) to the file.

Supplementary materials (optional)

Add datasets, code, or additional figures. Each file has a 100 MB limit. Supported formats: PDF, ZIP, TAR.GZ.

Step 6: Publication details

This step collects optional metadata about the eprint's publication and linked resources.

Code and data repositories

Link code and data repositories associated with your eprint. Each entry includes:

• URL: Link to the repository (e.g., https://github.com/user/repo)
• Platform: Select from the knowledge graph (GitHub, GitLab, Zenodo, Figshare, Dryad, OSF, Software Heritage, etc.)
• Label: Optional description (e.g., "Experiment scripts", "Training data")

You can add multiple code repositories and multiple data repositories.

Pre-registration

If your study was pre-registered, provide the registration URL and select the platform (e.g., OSF Registries, ClinicalTrials.gov, AsPredicted).

External IDs

Link your eprint to records on other platforms:

Field	Description	Autocomplete
arXiv ID	arXiv paper identifier (e.g., 2401.12345)	Yes
PMID	PubMed identifier	Yes
PMC ID	PubMed Central identifier	No
SSRN ID	SSRN paper identifier	No
OSF ID	Open Science Framework identifier	No
Zenodo DOI	Zenodo deposit DOI	No
OpenAlex ID	OpenAlex work identifier	No

Funding

Add funding sources with funder name, grant number, grant title, and grant URL.

Conference

If the eprint was presented at a conference, add the conference name, location, date, and presentation type.

Step 7: Classification

Select fields from the knowledge graph:

1. Type to search for fields
2. Click to select (maximum five fields)
3. Selected fields appear as tags
4. Click X to remove a field

Step 8: Review and submit

Review all information on the summary page. Click "Submit" to create the eprint record in your PDS.

After submission

Your eprint is indexed within minutes. You receive a permanent URL to share with colleagues.

Editing and versioning

You can edit your eprint metadata and upload new versions at any time. Each version uses semantic versioning (MAJOR.MINOR.PATCH) and supports structured changelogs. See Editing eprints for details.

Deleting

You can delete your eprint from Chive. The deletion propagates from your PDS to all indexers. See Editing eprints for details.

Multi-author submissions

For eprints with multiple authors:

1. One author (the submitter) creates the submission
2. Co-authors can claim their authorship through the claiming flow
3. The submitter can also send co-author requests to link verified accounts

Troubleshooting

Upload fails

Check file size (maximum 50 MB) and format (PDF only for main manuscript).

Cannot find field

If your field is not in the knowledge graph, propose it via the governance system.

Indexing delayed

New submissions typically appear within five minutes. If your eprint is not visible after one hour, contact support.
