In the process of developing StarView, which is the user interface to the Space Telescope Data Archive and Distribution Service (ST-DADS), these issues and the work of others were analyzed. Several archive/catalog groups, notably the Astrophysics Data System (ADS), are already working in many of these areas.

Software - public vs proprietary, client/ server software, standard interfaces to client/ server functions, software distribution, operating system portability, data portability, etc. Service Directory - service registration, lookup, port/task mapping, parameters, etc. Security - user registration, authorization/authentication mechanisms, etc. Interoperability - transaction/message protocols, distributed processing mechanisms (DCE, ONC/SunRPC, etc), networking protocols, etc. Catalog Access - database management systems, query languages, data formats, synchronous/asynchronous mode of operation, etc. The following issues (and probably more) need to be considered in establishing a standard set of client/ server interfaces and protocols: Archive Access - dataset retrieval, delivery, file formats, data browsing, analysis, etc. The primary services that are supplied by current systems include: catalog browsing, dataset retrieval, name resolution, and data analysis. Such a framework would simplify the development of client and server programs to access the wide variety of astronomical archive systems. Many of the issues involved in defining a standard framework of services that archive/catalog suppliers can use to achieve a basic level of interoperability are described. Some systems are moving towards distributed access, supplying users with client software for their home sites which connects to servers at the archive site. There are a large number of astronomical archives and catalogs on-line for network access, with many different user interfaces and features.

Recommendations for a service framework to access astronomical archives This software is the best for such purposes, and increasing supported catalogs and improvements of version 2.1 can cover a wider range of applications including advanced calibration system, scientific studies using complicated SQL queries, etc. Local databases are often indispensable for observatories with unstable or narrow-band networks or severe use, such as retrieving large numbers of records within a small period of time. We released 2MASS Catalog Server Kit version 2.1 in 2012 May, which supports the latest WISE All-Sky catalog (563,921,584 rows) and 9 major all-sky catalogs. Together with these, the powerful SQL environment of PostgreSQL will meet various user's demands. The kit provides highly optimized stored functions for positional searchs similar to SDSS Sky Server. This software utilizes the open source RDBMS PostgreSQL, therefore, any users can setup the database on their local computers by following step-by-step installation guide. The 2MASS Catalog Server Kit is open source software for use in easily constructing a high performance search server for important astronomical catalogs.
