- CA certificate
- A certificate that belongs to a CA and serves as the root certificate in a term:chain of trust.
A certificate authority is an entity that issues digital certificate s. The digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or assertions made by the private key that corresponds to the public key that is certified. In this model of trust relationships, a CA is a trusted third party that is trusted by both the subject (owner) of the certificate and the party relying upon the certificate. CAs are characteristic of many public key infrastructure (PKI) schemes.
- CA signing key
- The private key which the CA uses for signing CSRs.
A public key certificate (also known as a digital certificate or identity certificate) is an electronic document which uses a digital signature to bind a public key with an identity – information such as the name of a person or an organization, their address, and so forth. The certificate can be used to verify that a public key belongs to an individual.
- Chain of trust
The Chain of Trust of a Certificate Chain is an ordered list of certificates, containing an end-user subscriber certificate and intermediate certificates (that represents the Intermediate CA), that enables the receiver to verify that the sender and all intermediates certificates are trustworthy.
The CILogon project facilitates secure access to CyberInfrastructure (CI).
- An application that accesses the DataONE infrastructure on behalf of a user.
- Client Library
Part of the DataONE Investigator Toolkit (ITK). Provides programmatic access to the DataONE infrastructure and may be used to form the basis of larger applications or to extend existing applications to utilize the services of DataONE.
Available for Java and Python.
- Client side authentication
- SSL Client side authentication is part of the SSL handshake, where the client proves its identity to the web server by providing a certificate to the server. The certificate provided by the client must be signed by a CA that is trusted by the server. Client Side Authentication is not a required part of the handshake. The server can be set up to not allow Client side authentication, to require it or to let it be optional.
- Client side certificate
- Certificate that is provided by the client during client side authentication.
- Coordinating Node
- A server that implements the DataONE Coordinating Node API.
- Common Library
Part of the DataONE Investigator Toolkit (ITK). Provides functionality commonly needed by projects that interact with the DataONE infrastructure, such as serialization and deserialization of the DataONE types to and from types native to the programming language.
It is a dependency of DataONE Client Library.
Available for Java and Python.
TODO: We need to point to releases.dataone.org for the Common Libraries. For now, see https://repository.dataone.org/software/cicore/trunk/
- Coordinating Node API
The Application Programming Interfaces that Coordinating Nodes implement to facilite interactions with MN and DataONE clients.

Data Observation Network for Earth
- Data Packaging
Data, in the context of DataONE, is a discrete unit of digital content that is expected to represent information obtained from some experiment or scientific study.
- Distinguished Name
- The collection of Coordinating Nodes, Member Nodes, and applications (e.g. search interface) that work together as a federation. There is a single Production Environment and several test environments.
- environment dns
- Environment DNS
- The DNS entry that all systems interacting with CNs in and Environment
should use. During maintenance, the Environment DNS entry will be adjusted
to point to another CN in the same Environment, thus helping to ensure
ongoing availability of services while other CNs are offline. For example,
the DataONE Production Environment has three CNS,
cn-orc-1.dataone.org. The Environment DNS is
cn.dataone.organd points to one of the three CNs. The Environment DNS entry has a relatively short TTL, and its associated IPAddress should not be cached for more than a few seconds.
DataONE Generic Member Node
GMN is a complete implementation of a MN, written in Python. It provides an implementation of all MN APIs and can be used by organizations to expose their Science Data to DataONE if they do not wish to create their own, native MN.
GMN can be used as a standalone MN or it can be used for exposing data that is already available on the web, to DataONE. When used in this way, GMN provides a DataONE compatible interface to existing data and does not store the data.
GMN can also be used as a workbone or reference for a 3rd party MN implementation. If an organization wishes to donate storage space to DataONE, GMN can be set up as a replication target.
- Identity Provider
A service that authenticates users and issues security tokens.
In the context of DataONE, an Identity Provider is a 3rd party institution where the user has an account. CILogon acts as an intermediary between DataONE and the institution by creating X.509 certificates based on identity assertions made by the institutions.
- Investigator Toolkit (ITK)
The Investigator Toolkit provides a suite of software tools that are useful for the various audiences that DataONE serves. The tools fall in a number of categories, which are further developed here, with examples of potential applications that would fit into each category.
A statically typed programming language.
Levels of Assurance
CILogon operates three Certification Authorities (CAs) with consistent operational and technical security controls. The CAs differ only in their procedures for subscriber authentication, identity validation, and naming. These differing procedures result in different Levels of Assurance (LOA) regarding the strength of the identity contained in the certificate. For this reason, relying parties may decide to accept certificates from only a subset of the CILogon CAs.
- Member Node API
The Application Programming Interfaces that a repository must implement in order to join DataONE as a Member Node.
Metacat is a repository for data and metadata (documentation about data) that helps scientists find, understand and effectively use data sets they manage or that have been created by others. Thousands of data sets are currently documented in a standardized way and stored in Metacat systems, providing the scientific community with a broad range of Science Data thatâ€“because the data are well and consistently describedâ€“can be easily searched, compared, merged, or used in other ways.
Metacat is implemented in Java.

Resource Description Framework
The Resource Description Framework (RDF)  is a family of World Wide Web Consortium (W3C) specifications  originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax notations and data serialization formats.
- Read Only
- read-only mode
- The state of an environment when updates to content throught the DataONE
service interfaces is disabled. Services including
searchcontinue to function enabling user access to the content without disruption.
- Replication target
- A MN that accepts replicas (copies) of Science Data from other MNs and thereby helps ensuring that Science Data remains available.
- Resource Map
Representational State Transfer
A style of software architecture for distributed hypermedia systems such as the World Wide Web.
- Science Data
- An object (file) that contains scienctific observational data.
- Science Metadata
- An object (file) that contains information about a Science Data object.
In DataONE, a subject is a unique identity, represented as a string. A user or Node that wishes to act as a given subject in the DataONE infrastructure must hold an X.509 certificate for that subject.
DataONE defines a serialization method in which a subject is derived from the DN in a X.509 certificate.
- Self signed certificate
A certificate that is signed by its own creator. A self signed certificate is not a part of a chain of trust and so, it is not possible to validate the information stored in the certificate. Because of this, self signed certificates are useful mostly for testing in an implicitly trusted environment.
- Server key
- The private key that Apache will use for proving that it is the owner of the certificate that it provides to the client during the SSL handshake.
- Server Side Authentication
- SSL Server Side Authentication is part of the SSL handshake, where the server proves its identity to the client by providing a certificate to the client. The certificate provided by the server must be signed by a CA that is trusted by the client. Server Side Authentication is a required part of the handshake.
- Server side certificate
- Certificate that is provided by the server during server side authentication.
Secure Sockets Layer
