L&B
Logging and Bookkeeping (L&B)
Logging and Bookkeeping (LB for short) is a Grid service that keeps a short-term trace of Grid jobs and other grid-related processes as they are processed by individual Grid components. The LB was initially developed in the EU DataGrid project as a part of the Workload Management System (WMS). The development continued in the EGEE project (EGEE-II, EGEE-III respectively), where LB became an independent part of the gLite middleware. Currently we are participating in the EMI project ( see LB status in EMI, gLite Logging and Bookkeeping Product Team).
UNICORE
Uniform Interface to Computing Resources (UNICORE)
UNICORE (Uniform Interface to Computing Resources) offers a ready-to-run Grid system including client and server software.
UNICORE makes distributed computing and data resources available in a seamless and secure way in intranets and the internet.
UNICORE has special characteristics that make it unique among Grid middleware systems. The UNICORE design is based on several guiding principles, that serve as key objectives for further enhancements.

LFC
LCG File Catalog (LFC)
The LCG File catalogue (LFC) offers a hierarchical view of files to users, with a UNIX-like client interface. The LFC catalogue provides:
- Logical File Name (LFN) to Storage URL (SURL) mappings (via a GUID);
- Authorisation on its logical
DPM
Disk Pool Manager (DPM)
The Disk Pool Manager (DPM) is a lightweight storage solution for grid sites. It offers a simple way to create a disk-based grid storage element and supports both standard (HTTP/S, NFS 4.1/pNFS) and grid specific protocols (SRM, gridFTP, XROOTD, RFIO) for file management and access.
GFAL 2.0
GFAL 2.0
GFAL2 is a framework for Grid and Cloud file access, file transfer and file management.
The GFAL 2.0 library :
The GFAL 2.0 library (gfal2-core) provides a unified and protocol-generic API for file access, file transfer and file management operations in Grid and Cloud environments. GFAL 2.0 allows to build applications using the Grid technologies ( file, GridFTP, RFIO, Dcap, SRM, LFC, Http/Dav, xrootd ) in a transparent manner.
The GFAL 2.0 transfer library:
The GFAL 2.0 transfer library (gfal2-transfer) is an addit
Grid Information System
Grid Information System
The Grid Information System provides detailed information about grid services. The Grid Information System system has a hierarchical structure of three levels. The fundamental building block used in this hierarchy is the Berkley Database Information Index (BDII). Although the BDII has additional complexity, it can be visualized as an LDAP
FTS
File Transfer Service (FTS)
FTS is the service responsible for distributing the majority of LHC data across the WLCG infrastructure. It is a low level data movement service, responsible for moving sets of files from one site to another while allowing participating sites to control the network resource usage. This control includes the enforcement of site and usage policies like fair-share mechanisms on dedicated network links.
D-Net
D-Net Software toolkit (D-Net)
The D-Net Software Kit is an Open Source service-oriented solution for the construction of customized Data Infrastructures. D-NET provides a service-oriented framework where data infrastructures can be constructed in a LEGO-like approach, by selecting and properly combining into data processing workflows the D-NET services required.

Argus
Argus Authorization Service (Argus)
The Argus Authorization Service renders consistent authorization decisions for distributed services (e.g., user interfaces, portals, computing elements, storage elements). The service is based on the XACML standard, and uses authorization policies to determine if a user is allowed or denied to perform a certain action on a particular service. The Argus Authorization Service is composed of three main components:
- The Policy Administration Point (PAP) provides the tools to author authorization policies, organize them in the local repository and configure policy distribution among
