[Web Architecture]关于 file scheme 即 file://<host>/<path>

* http://www.faqs.org/rfcs/rfc1738.html   {{//Section 3.10 of RFC1738

The file URL scheme is used to designate files accessible on a
   particular host computer. This scheme, unlike most other URL schemes,
   does not designate a resource that is universally accessible over the

   A file URL takes the form:


   where <host> is the fully qualified domain name of the system on
   which the <path> is accessible, and <path> is a hierarchical
   directory path of the form <directory>/<directory>/.../<name>.

   For example, a VMS file


   might become


   As a special case, <host> can be the string "localhost" or the empty
   string; this is interpreted as `the machine from which the URL is
   being interpreted'.

   The file URL scheme is unusual in that it does not specify an

[SWS]OWL-S中 parameterValue Property的作用

Parameter类有两个Properties: parameterType ( minCardinality 1 ) parameterValue (在过去的版本中用于制定constant value)
I brought this up a while ago on this list, and no-one objected to deprecating this property, since we have valueData to do the job.
parameterValue is a leftover from earlier incarnations of OWL-S. /Daniel
Maybe the definition of the parameterValue needs to be changed as the "default value" that will be used in case no other value is provided. In any case, a clarification about its use needs to be documented. Evren


  是上次升级代码时,不小心留下的一只bug. 刚才上来时发现已经两天没有新日志了,顿生疑虑。。。 查看了一下代码,果然是一只bug。 造成大家两天不能正常使用,真过意不去了。 还望大家包涵!


 Concerning the inputs and outputs, the philosophy (and practice) in OWL-S is that the I/O is in terms of functional capability not low level details like account number and password. In other words, the inputs and outputs should differentiate one service (e.g. buying a tennis racket) from another (e.g. buying shoes) whereas giving a credit card or a password does not differentiate between the two services. It is the role of the process model in OWL-S to break down the buying of a tennis racket into a login atomic process where account number and password are needed, and then the selection part where the particular type of tennis racket is input, and then the actual buying part where your credit card is input.

1. 简介 并没有什么神丹妙药可以保证在研究中取得成功,本文只是列举了一些可能会有所帮助的非正式意见。
本文档被粗略地分为两部分。第一部分涉及研究者所需具备的各种技能:阅读, 写作和程序设计,等等。第二部分讨论研究过程本身:研究究竟是怎么回事,如何做研究,如何选题和选导师,如何考虑研究中的情感因素。很多读者反映,从长远看,第二部分比第一部分更有价值,也更让人感兴趣。
l         如何通过阅读打好AI研究的基础。列举了重要的AI期刊,并给出了一些阅读的诀窍。
l         如何成为AI研究领域的一员:与相关人员保持联系,他们可以使你保持对研究前沿的跟踪,知道应该读什么材料

[Cloud Computing]WSRF

转载自: http://looselycoupled.com/glossary/WSRF

WSRF (Web Services Resource Framework) Web services for grid computing. WSRF defines conventions for managing 'state' so that applications can reliably share changing information. In combination with WS-Notification and other WS-* standards, the result is to make grid resources accessible within a web services architecture. Coupled with WS-Notification, the specification is a response to, and supersedes, the grid community's own first effort to converge grid and web services, the Open Grid Service Infrastructure (OGSI), which the Global Grid Forum (GGF) and others released in 2003. Announced by the Globus Alliance and IBM (with contributions from HP, SAP, Akamai, Tibco and Sonic) in January 2004, WSRF is due to be implemented in version 4.0 of the open source Globus Toolkit for grid computing, as well as several commercial packages. It consists of several component specifications, including WS-Resource Properties, WS-ResourceLifetime, WS-ServiceGroup and WS-BaseFaults.

[SWS]asymmetric vs. symmetric matching

Asymmetric matching: the provider-published description of its properties is queried by the consumer to identifiy candidates prior to generating requests for resource. Symmetric matching: resource and request are descrbed by the same syntax. The request describes its requirement to the resource while the resource describes its requirement ( or policy ) to the requester.
