\section{ObsCore Table Model}

ObsCore defines a simple set of core attributes to be included in a single table. This table structure can be
implemented in various services.

TODO: move core specification content from next section here

\section{Implementation of ObsCore in a TAP Service}
TODO: TAP-specific details here

\label{sec:obstap-impl}The ObsCore model must be implemented within Table Access Protocol (TAP) services such that all
valid queries can be executed unchanged on any service that implements the model. Additional optional or
provider-defined columns are permitted (see section \ref{bkm:Ref421295535}) so long as all mandatory columns are

ones. Queries built up using additional columns defined specifically for a given archive might not be portable.

\section{Registering an ObsTAP Service}
\section{ObsCore Extensions}
The ObsCore table includes common metadata attributes that are applicable to a wide range of astronomical data.
Additional details that are not common enough to be included in core may be defined as extensions that support
data discovery use cases for specific kinds of data.

TODO: write this section following current practice and remove the next section.

\section{OBSOLETE: Registering an ObsTAP Service}
TODO: remove when previous section makes it obsolete

\label{sec:obstap-register}The standard identifier for this version of the ObsCore model now follows the IVOA Identifiers
v2.0 specification \citep{2016ivoa.spec.0523D} and should be ivo://ivoa.net/std/ObsCore\#core-1.1
