Hello — the namespace of the lsid.
hello—该LSID的名称空间。
Unlike the data associated with an LSID, metadata can expire.
和与LSID关联的数据不同，元数据会到期。
Suppose that the LSID urn:lsid:pets.org:cats:Tom names a cat.
假定LSID urn:lsid:pets.org:cats:Tom 给一只猫取名字。
The LSID Client Stack and Server Framework handle these two cases.
这两种验证由LSID客户端堆栈和服务器框架负责完成。
The "server" side of this resolver solution is called an LSID authority.
这一解析器解决方案的“服务器”端名为LSID中心(LSID authority)。
Metadata about a particular LSID consists of a collection of RDF statements.
关于某一特定LSID的元数据由一组rdf语句组成。
If you decide to test with an LSID that has associated data, you can try the command.
如果决定对具有关联数据的LSID进行测试，可以尝试使用命令。
The first, illustrated in Figure 3, is to provide an LSID-based view of a local data store.
第一个用例见图3，是用来提供本地数据存贮的一个基于LSID的视图。
The following examples of LSID Resolution Services show how the LSID Server Framework can be used.
接下来的LSID解决方案服务的例子会说明如何使用LSID服务器框架。
Any organization with a bit of work or outsourcing could provide their existing databases via LSID.
任何一个组织只需要少量的工作或者通过外购就可以通过LSID将他们现有的数据库提供出来。
Utopic visions aside, LSID Resolution will become more useful when more providers use LSIDs to expose their data.
即便不考虑理想的完美境界，随着更多的提供者使用LSID来公开他们的数据，LSID解决方案也将变得理更加有用。
Finally, we'll see how enterprises might integrate these components to form an enterprise LSID Resolution Network.
最后，我们将看到企业如何集成这些组件来构建一个企业级LSID解决方案网络。
Instead of specifying locations for metadata, it specifies locations where data associated with an LSID can be obtained.
它并不指定元数据的位置，而是指定可以在哪里获得与LSID关联的数据。
Each servlet parses the method, arguments, and target LSID (which may be a SOAP parameter or part of the URL) from a request.
每个servlet从请求中解析出方法、参数和目标l SID(可能是一个SOAP属性或部分URL)。
Using the target LSID, the servlet looks in the service registry to determine which configured service implementation to invoke.
Servlet使用目标LSID在服务注册表中查找并确定要调用的已经配置的服务实现。
You are asking DNS for the lsid service record for pdb.org with TCP as the network protocol. The response should look like this.
您正在向DNS询问使用TCP作为网络协议的pdb.org的lsid服务记录。
All LSIDs with authority myauth will be handled by the Local LSID Services. All other LSIDs will be handled by the Caching Proxy.
所有的带有myauth中心的LSID被本地LSID服务处理，所有其它的LSID由缓存代理来处理。
That means that the metadata about an LSID is the perfect location for storing transient information about the object in question.
这意味着关于某一LSID的元数据是存储所关注对象的瞬态信息的极佳位置。
We implement the LSIDDataService interface and pass it as a parameter to the DataServlet servlet class provided by the LSID package.
我们实现LSIDDataService接口，并将其作为参数传递至LSID包提供的DataServletservlet类。
The caching proxy can process any LSID that is resolvable via DNS, so its list of known URIs is technically the global space of LSIDs.
缓存代理能处理任何可以通过DNS解析的LSID，所以它的已知uri列表在理论上是LSID全局空间的列表。
Since Tom's photo has data associated with it, we must describe that fact in our metadata. The class urn: lsid: i3c.org: types: content.
因为Tom的照片有与其关联的数据，所以我们必须在元数据中描述这一事实。
In addition to this symmetry, the client applications can access external LSID-based data sources such as PDB and Gateway-based services.
作为对这种对称结构的补充，客户端应用程序可以访问外部的基于LSID的数据源，比如pdb和基于网关的服务。
Certain data sources will require only mapping from LSID to URL, if each piece of data has a URL that can retrieve it in a standard format.
如果每一“块”数据有一个URL来以标准格式提取数据，那么这些特定的数据源只需要从LSID映射到URL就可以实现服务。
Furthermore, the proxy can cache all of its requests so that scientists using the same LSID working set will experience rapid respond time to requests.
此外，代理可以缓存它的所有的请求，这样使用相同LSID数据集的科学家发送的请求可以得快速的响应。
The subject and predicate are always named by a URI, and since an LSID is a URN, which is a kind of URI, LSIDs can be used as either RDF statements or predicates.
主语和谓语始终由URI命名，由于LSID是一个URN，而URN是一种URI，所以LSID既可用作rdf语句，也可用作谓语。
The LSID Server Framework enables this LSID utopia by allowing organizations to provide their data using a service implementation that best matches their data source.
LSID服务器框架允许各个组织以最适合本身数据源的服务实现来为彼此提供数据，从而使得这个LSID “乌托邦”得以实现。
To take the authority for pdb.org as an example, you should be able to determine the host name and port number where the LSID service resides. Enter the following command.
以pdb.org中心为例，您应该能够确定LSID服务所驻留的主机名和端口号。
Using SimpleAuthority, the developer need only implement methods that return the locations of metadata and data for a given LSID. This information is used to construct WSDL.
使用SimpleAuthority，开发者只需要实现方法来返回给定lsid的元数据和数据的位置信息，根据这些信息用来构造WSDL。
For example, urn: lsid: pdb.org: PDB: 1aft might be handled by PDBAuthorityImpl, whereas urn: swiss-prot.org: swiss-id: hv20_mouse-sprot might be handled by SWISSAuthorityImpl.
例如，urn：lsid：pdb.org： pd b：1aft可能会由pdbauthorityimpl处理，而urn：swiss-prot.org： swiss - id： hv 20_mouse - sprot可能会由SWISSAuthorityImpl来处理。
After verifying the existence of the given LSID, we return an array containing a single location: the endpoint of our metadata service. The following line needs some elaboration.
在验证给定的LSID是否存在之后，我们返回包含单个位置(元数据服务的端点)的数组。
