hypercat.py 0.1.2

起源

这个模块是一个简单的hypercat模块的重新打包 这里：https://github.com/hypercatIoT/python-tools

用例

服务器：

• 创建一个空的hypercat目录
• 或者，添加元数据来描述它
• （可选）将项目添加到目录
  • 项目是另一个目录或资源
• 将其输出为json，可以是最小的，也可以是预打印的
• 查找目录层次结构的特定部分

客户：

• 加载并验证hypercat

示例-hypercat服务器

我们将创建一个包含两个项目的hypercat目录：

  h
 / \
h2  r

用法：

from hypercat import hypercat

# Create a catalogue
h = hypercat.hypercat("CatalogueContainingOneCatalogueAndOneResource")

# Create a second catalogue, and add it as a child of the first
h2 = hypercat.hypercat("ChildCatalogue")
h.addItem(h2, "/child_cat")

# Create a resource, and add it as another child of the first catalogue
r = hypercat.resource("resource1", "application/vnd.hypercat.sensordata+json")
h.addItem(r, "/resource")

# Print the raw JSON of the catalogue, and then with human-friendly formatting
print h.asJSON()
print h.prettyprint()

这应该输出：

{
    "catalogue-metadata": [
        {
            "rel": "urn:X-hypercat:rels:isContentType",
            "val": "application/vnd.hypercat.catalogue+json"
        },
        {
            "rel": "urn:X-hypercat:rels:hasDescription:en",
            "val": "CatalogueContainingOneCatalogueAndOneResource"
        }
    ],
    "items": [
        {
            "href": "/child_cat",
            "item-metadata": [
                {
                    "rel": "urn:X-hypercat:rels:isContentType",
                    "val": "application/vnd.hypercat.catalogue+json"
                },
                {
                    "rel": "urn:X-hypercat:rels:hasDescription:en",
                    "val": "ChildCatalogue"
                }
            ]
        },
        {
            "href": "/resource",
            "item-metadata": [
                {
                    "rel": "urn:X-hypercat:rels:isContentType",
                    "val": "application/vnd.hypercat.sensordata+json"
                },
                {
                    "rel": "urn:X-hypercat:rels:hasDescription:en",
                    "val": "resource1"
                }
            ]
        }
    ]
}

示例-hypercat客户端

用法：

from hypercat import hypercat

h = hypercat.loads(inString)  # Read-in and validate Hypercat
print "Metadata is ",h.metadata
