    "abstract": "The POOL project has been created to implement a common persistency framework\nfor the LHC Computing Grid (LCG) application area. POOL is tasked to store\nexperiment data and meta data in the multi Petabyte area in a distributed and\ngrid enabled way. First production use of new framework is expected for summer\n2003. The project follows a hybrid approach combining C++ Object streaming\ntechnology such as ROOT I/O for the bulk data with a transactionally safe\nrelational database (RDBMS) store such as MySQL. POOL is based a strict\ncomponent approach - as laid down in the LCG persistency and blue print RTAG\ndocuments - providing navigational access to distributed data without exposing\ndetails of the particular storage technology. This contribution describes the\nproject breakdown into work packages, the high level interaction between the\nmain pool components and summarizes current status and plans.",
