| <ul><li> <b>Action</b> - An action is one step in an <a href="Glossary.html#W" title="">asynchronous workflow</a> associated with a certain <a href="Glossary.html#W" title="">worker</a> that does the actual processing. |
| </li><li> <b>Agent</b> (deprecated) - An agent is a component of the connectivity framework that monitors a data source for changes (or reacts to events). If a change occurs (e.g. objects are created, deleted, or changed) it immediately creates a <a href="Glossary.html#R" title="">record</a> out of the object and sends it to SMILA. Agents are used to watch data sources for modifications, not for bulk import. |
| </li><li> <b><a href="http://aperture.sourceforge.net/" class="external text" title="http://aperture.sourceforge.net/" rel="nofollow">Aperture</a></b> - Aperture is a Java framework for extracting and querying full-text content and metadata from various information systems (e.g. file systems, web sites, mail boxes) and the file formats (e.g. documents, images) occurring in these systems. |
| </li><li> <b>Attachment</b> - Attachments are parts of <a href="Glossary.html#R" title="">records</a> used to store large binary data such as document content. |
| </li><li> <b>Attribute</b> - Attributes are parts of <a href="Glossary.html#R" title="">records</a> and contain simple data objects that are easily represented in XML or json, such as <tt>String</tt>, <tt>Integer</tt>, <tt>Float</tt>, and <tt>Date</tt>. |
| </li></ul> |
| <a name="B"></a><h2> <span class="mw-headline"> B </span></h2> |
| <ul><li> <b>Blackboard</b> or <b>blackboard service</b> - The blackboard service manages SMILA <a href="Glossary.html#R" title="">records</a> during processing in a SMILA component (connectivity, workflow processor). In addition it hides the handling of record persistence from these components. For a complete description see <a href="Documentation/Usage_of_Blackboard_Service.html" title="SMILA/Documentation/Usage of Blackboard Service">Usage of Blackboard Service</a>. |

It defines a set of basic control structures like conditions or loops as well as elements to invoke web services and receive messages from services. It relies on <a href="Glossary.html#W" title="">WSDL</a> to express web services interfaces. Message structures can be manipulated, assigning parts or the whole of them to variables that can in turn be used to send other messages. |
| </li></ul> |
| <ul><li> <b>Bucket</b> - Data container in an <a href="Glossary.html#W" title="">asynchronous workflow</a>, containing logically grouped <a href="Glossary.html#D" title="">data objects</a> of the same type. Can be <i>transient</i> for interim data, which means that data is not persisted and removal of data is under job management control, or <i>persistent</i>, which means that removal of data is not under job management control. |
| </li></ul> |
| <ul><li> <b>Bulk</b> - a number of <a href="Glossary.html#R" title="">records</a> bundled in a single file to enhance throughput when processing records in <a href="Glossary.html#W" title="">asynchronous workflows</a>. |

| <a name="C"></a><h2> <span class="mw-headline"> C </span></h2> |
| <ul><li> <b>Crawler</b> - A crawler is a component that iterates over the elements (e.g. files) of a data source, creates <a href="Glossary.html#R" title="">records</a> for all elements and sends them to SMILA (e.g. for file and web crawling). In general crawlers are used for initial (bulk) import of data sources. Two kind of crawlers exist |
| <ul><li> An <a href="Glossary.html#W" title="">asynchronous workflow</a> <a href="Glossary.html#W" title="">worker</a> (<tt>FileCrawlerWorker</tt>, <tt>WebCrawlerWorker</tt> (see <a href="Documentation.1.html#Importing" title="SMILA/Documentation">Importing</a>) that creates records (with e.g. URL/Path, ID, a hash value and the metadata it can retrieve, optionally with content) that can be checked by the <a href="Glossary.html#D" title="">DeltaChecker</a> if it must be updated. The content will be fetched (if the crawler does not provide it itself) by a <a href="Glossary.html#F" title="">Fetcher</a>. |

SCA extends and complements prior approaches to implementing services, and SCA builds on open standards such as web services. The SCA programming model is highly extensible and is language-neutral. Go to <a href="http://wiki.eclipse.org/index.php?title=SMILA/Project_Related_Technologies/SCA_and_Tuscany&action=edit" class="new" title="SMILA/Project Related Technologies/SCA and Tuscany">SCA and Tuscany</a> for discussing. |

Using SDO, application programmers can uniformly access and manipulate data from heterogeneous data sources, including relational databases, XML data sources, web services, and enterprise information systems. The SDO programming model is language neutral. |

| <ul><li> <b>Slot</b> - An (input/output) slot is a description for the input/output behaviour of a <a href="Glossary.html#W" title="">worker</a>. In a concrete <a href="Glossary.html#W" title="">asynchronous workflow</a> slots are assigned to <a href="Glossary.html#B" title="">buckets</a> |

| <ul><li> <b><a href="http://www.osoa.org/display/Main/Home" class="external text" title="http://www.osoa.org/display/Main/Home" rel="nofollow">SOA</a></b> - Service-Oriented Architecture is a computer systems architectural style for creating and using business processes, packaged as services, throughout their lifecycle. SOA also defines and provisions the IT infrastructure to allow different applications to exchange data and participate in business processes. These functions are loosely coupled with the operating systems and programming languages underlying the applications. |
| </li></ul> |
| <ul><li> <b>Surrogate process</b> - A surrogate process is a process that embeds several components. Additionally this process adds further functionality to these components (e.g. runtime functionality, error prevention, transactions, manageability ...). In the SMILA application surrogate processes also add business processes and further features (e.g. callability from external processes or applications...). |

The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint. Related concrete endpoints are combined into abstract endpoints (services). WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate. |
