    99'''Renewal:''' Slices and slivers are created with a particular expiration time, which is aggregate-specific. An experimenter may request that the expiration time be extended by a renewal request. Once the expiration time of a given slice or sliver has passed, however, these elements can no longer be renewed and may be reclaimed by GENI.

    11 '''RSpec:''' Resources in GENI are described in XML files called Resource Specifications (RSpecs). Aggregate resource listings (advertisements), reservation requests, and manifests of resources you have reserved are all represented as RSpecs.

    1313'''Slice:''' A slice is the context for a particular set of experiments, and contains reserved resources and the set of GENI users ('members') who are entitled to act on those resources. A slice belongs to a single project, and can have multiple members. Experimenters can add and delete resources from a slice.
     
    1919'''Sliver:''' A Sliver is one or more resources provided by an aggregate, whether virtual or whole ('bare metal'). Slivers are created and added to Slices through calls to the Aggregate Manager API at aggregates. Slivers are isolated from other slivers on the same resources.

    21 '''SSH Keys:''' These are PKI (Public Key Infrastructure) public/private key pairs that represent a user's identity for logging into a remote computer. Typically, the public key is stored on the remote computer and the private key is held by the user trying to 'ssh' (secure remote login). See en.wikipedia.org/wiki/Secure_Shell. When slivers are created for compute resources, tools (such as the GENI portal) can provide the aggregate with a set of public SSH keys, enabling experimenters to securely log in to the reserved compute resources.

    2323'''SSL Key and Certificate:''' These are PKI (Public Key Infrastructure) materials representing a user's identity for SSL (secure sockets layer) communications such as HTTPS sessions. Specifically the AM API requires authentication by means of SSL client certificates signed by a trusted GENI root.
