IEDA Data Publication Policy

Version 1.0, 2/15/2012 [download PDF version]

IEDA maintains open-access data repositories, synthesis databases, tools, and other digital resources relevant to a wide range of geoscience data. IEDA guarantees long-term availability of its content through partnerships with the Columbia University Libraries and the National Geophysical Data Center.

IEDA believes that data should be published and cited in just the same way that other sources of information, such as articles and books, can be cited. Data citation enables easy reuse and verification of data, allows the impact of data to be tracked, and creates a scholarly structure that recognizes and rewards data producers (see

IEDA publishes datasets submitted to IEDA data repositories by registering dataset metadata with the Digital Object Identifier (DOI®) system via the DataCite Managing Agent TIB (German National Library of Science and Technology). The DOI® System is for identifying content objects in the digital environment. Upon registration of the metadata, the dataset is assigned a persistent (a DOI®) that resolves to a public IEDA page that contains information about the associated dataset and a direct link to the dataset itself. A dataset submitted to IEDA data repositories is only registered with the DOI® system when (a) it has been approved by IEDA, and (b) the author has approved its release to the general public.

IEDA data is available under a Creative Commons License (CC BY-NC-SA 3.0) which means that use of the data must be accompanied by proper citation. IEDA‘s recommended format for a data citation follows the format recommended by DataCite:

Creator (PublicationYear): Title. Publisher. Identifier

Example: Ryan, William B.F., et al. (2009): Global Multi-Resolution Topography (GMRT). Lamont-Doherty Earth Observatory. doi:10.1594/IEDA.0001000.


Documentation of the Dataset

IEDA distinguishes between two different types of dataset documentation:

(a) Cataloging metadata, e.g. AUTHOR, TITLE, DATA TYPE, DATE OF SUBMISSION: IEDA uses a mandatory core set of metadata and optional fields that further explain the relationships of the datasets to publications and other datasets, as defined by the DataCite metadata kernel (
Cataloging metadata include the DOI® of the publication associated with the dataset.

(b) Data specific documentation that is relevant for evaluation and re-use of the data, e.g. method, precision, etc.
Requirements for data specific documentation follow disciplinary rules for the different fields. Please visit for further information.


Steps for Dataset Publication

Datasets submitted to IEDA undergo the following process to become officially published with a DOI:

1. Submission: Author submits Cataloging Metadata and dataset file to IEDA. Once IEDA approves the dataset, dataset metadata are viewable by the public. The dataset itself becomes accessible to the public on a Publication Date that is set by the author. Until the Publication Date, the author may make revisions to the dataset.

2. Publication: On the Publication Date, the dataset is released to the public under the Creative Commons License, the metadata registered with the DOI® system, and the datasets is assigned a DOI®. At this point, no further edits shall be made to the dataset. If any changes are necessary, a new version of the dataset must be submitted and registered.

3. Withdrawal: If necessary, a dataset may be withdrawn. Its Cataloging Metadata will remain in the system, clearly marked as “Withdrawn.”
