+\section*{\docTitle}
 
-\begin{enumerate}
+\subsection*{Science Data Centre Context \& Governance}
 
-  \item{Edit \verb|Makefile| and set \verb|DOCHANDLE| to the appropriate handle for your document.
-        Refer to the \href{https://support.astron.nl/confluence/display/SDCP/List+of+SDC-Series+Documents}{list of SDC series documents} which have been issued to date, and choose the next one in sequence.}
+The Science Data Centre is a new facility which aims to be the single point of contact for users of instrumentation operated by ASTRON.
+It will ultimately provide services including --- but not limited to --- proposal preparation and submission; archiving and providing access to data; generation of science-ready data products; user-friendly interfaces to discover and access data; and on-line interactive analysis facilities.
 
-  \item{Check the preamble of this file to ensure that the document title, programme, and author(s) have been set correctly.}
+As an facility, the SDC is run by an operational unit within ASTRON's Astronomy \& Operations department: the SDC Operations team.
+The facility is developed and supported by the SDC Development Program, which draws on staff from across the institute.
 
-  \item{Insert your text here.}
+The SDC was formed in 2020, inheriting a complex service portfolio from its predecessors within ASTRON.
+During 2021, our activities have included both establishing the organizational structures on which the SDC will be built and managed, on a number of high-impact technical deliverables, and on engagement with a number of major international projects.
 
-  \item{Use the \verb|\gls| command to refer to abbreviations, like \gls{SDC}.}
+\subsection*{Scaled Agile Framework}
 
-  \item{Use the \verb|\autocite| command to cite other documents, like \autocite{SDC-006}.}
+The SDC Program has adopted an organization based on the \emph{Scaled Agile Framework}\footnote{\url{https://scaledagileframework.com}}, or SAFe.
+The SAFe system was chosen because it provides best-practice structures for organizing agile software development at scale in a way which focuses both on quality and on responsiveness to customer needs.
+Further, SAFe has been shown to be very successful in the scientific context by our peers and colleagues in the Square Kilometre Array project\footnote{\url{https://www.skatelescope.org/}}.
 
-  \item{Use the \verb|\cref| command to refer to sections, tables, or other material in this document, like \cref{sec:getting-started}.}
+Adopting SAFe has required a substantial effort in training and adapting our ways of working during 2021, but initial results have been very positive and the SDC Program enters 2022 with a solid organizational structure and confidence that we are ready to tackle the challenges of SDC construction!
 
-  \item{Run \verb|make| to compile the document.}
+\subsection*{Pipeline Execution Framework}
 
-\end{enumerate}
+During early 2021, the SDC Program delivered the \emph{ATDB-LDV} pipeline execution framework to operations.
+\emph{ATDB-LDV} provides a standardized systems for processing data within the operational SDC facility.
+Throughout 2021, it has been used by the \emph{LOFAR Data Valorisation} project in support of ongoing processing campaigns.
+We expect that development of the framework will continue, and further pipelines will be integrated with it, during 2022.

+\subsection*{Prefactor Pipeline}
+
+\emph{Prefactor} is a pipeline for direction-independent calibration and imaging of LOFAR data.
+It is the result of several years of development effort, both within ASTRON and across the broader community of LOFAR users, and draws on a number of standard software components developed by ASTRON's Smart Backend group and its partners.
+
+During 2021, the SDC team accepted responsibility for continued development and maintenance of Prefactor.
+It has been updated so that it is now defined using the Common Workflow Language\footnote{\url{https://www.commonwl.org}}, which forms the basis of the pipeline execution system used by the SDC facility.
+
+This updated Prefactor pipeline was made available in late 2021, and, at time of writing, is undergoing integration with the \emph{ATDB-LDV} execution framework.
+During 2022, it will form the basis of processing carried out by the \emph{LOFAR Data Valorisation} project.
+
+\subsection*{SKA Regional Centres}
+
+When it becomes operational in the second half of this decade, the Square Kilometre Array will generate enormous quantities of data.
+The SKA Observatory itself will not make this data directly available to end users.
+Rather, it will be supplied to a globally-distributed network of \emph{SKA Regional Centres} which are responsible for archiving the data and supporting end-user science activities.
+
+Construction of this SRC network is a major international effort, involving stakeholders and technical teams from across the various members of the SKA.
+The SDC Program, in collaboration with the SDCO Operations team and ASTRON's SKA-SDC Focus Group, are leading ASTRON's contribution to the SRC design effort.
+During 2021, this has involved collecting system requirements and developing initial architectural concepts.
+This work will continue into 2022, as we move towards a large-scale prototyping effort.
+
+\subsection*{Science Analysis Platform}
+
+The ESCAPE Project\footnote{European Science Cluster of Astronomy \& Particle Physics ESFRI Research Infrastructures; \url{https://www.projectescape.eu}} is developing common digital infrastructure for use by major research infrastructure projects across Europe.
+The SDC Program leads ESCAPE's Work Package 5, which is developing a science analysis platform framework.
+This provides data discovery, access, and analysis services across a wide range of science cases and communities.
+
+During 2021, development of this system continued rapidly, reaching a culmination in an international workshop in August which demonstrated an impressive range of functionality and received positive feedback from the community.
+A test version of the platform is has been made available online available\footnote{\url{https://sdc-dev.astron.nl/esap-gui/}, but note that this is strictly a development system and availability and functionality is not guaranteed.}, and work is now underway to develop an ASTRON-specific version which will be deployed within the operational SDC facility (known as ADEX, the ASTRON Data Explorer).
+
+\subsection*{LoTSS Data Release 2 and Scientific Data Repositories}
+
+LoTSS, the LOFAR Two-metre Sky Survey, is a major wide-area imaging survey carried out in the LOFAR high band.
+Data processing for the survey has been coordinated by the LOFAR Surveys Key Science Project.
+The SDC team has coordinated hosting and publication of the second data release through a scientific data repository hosted at SURF (although at time of writing the data is embargoed pending publication of an accompanying scientific paper).
+
+Deployment of this form of repository at SURF is a key technological step for our SDC plans, and paves the way to our support of future data releases.
+It is also a great example of cooperation between the ASTRON SDC, the scientific community using LOFAR, and SURF, the national e-infrastructure provider, a mode of operation which we regard as vital to the success of the SDC effort and the scientific productivity of the community.
